Error when installing

[thienhaxanh2405]

I've installed this on a site of my WPMU network, but catch a fatal error.
This's through message:

Please check out and guide me to install again.
Thank you.

@thienhaxanh2405 Thanks for reporting. What version of PHP, MySQL, and WordPress are you running please. Thanks in advance for those necessary details! :-)

[thienhaxanh2405]

@jaswsinc my server's runing:
nginx 1.6.3
PHP 5.4.15
MySQL 5.5.44
Wordpress 4.4.1

[jaswrks]

Thanks! Those all look adequate. We have tested Comment Mail tables going back as far as MySQL 5.1, and your version of PHP and WordPress look good also.

Can you trying adding define( 'WP_DEBUG', true ); to your /wp-config.php file and test this again for me? I'm hoping that will give you more details about what is causing that DB table creation error on your installation specifically. See also: https://codex.wordpress.org/Debugging_in_WordPress

If running in debug mode doesn't give you any more information, please write me back and we can try sending you a slightly modified copy that will log some additional details for us to review with you.

[thienhaxanh2405]

I've turned on debug mode, and, unfortunately, still exception message

Thanks :-)

I dont understand PHP and MySQL, but it makes me feel that it tries to write into .sql file in the file directory instead of writing into Wordpress database.

[jaswrks]

@thienhaxanh2405 Here is a copy of the installer.php file that has been modified to print the specific MySQL error that occurs. If you can download the file and upload via FTP, letting this override your existing copy of comment-mail/includes/classes/installer.php, perhaps it will shed light.

https://gist.github.com/jaswsinc/761812edb592733bc3a9

[thienhaxanh2405]

@jaswsinc sorry, no more information yet :(. I've tried, die after $this->plugin->utils_db->wp->print_error(); - line 62, but nothing prints out.
I think about plugins confliction, and Deactivate all, but your plugin still doesn't work.

[thienhaxanh2405]

oh, sorry, I'm running Comment Mail Pro, version 160213. I forgot to mention you about my version.

[jaswrks]

but nothing prints out.

I updated the Gist to include show_errors() as well.
https://gist.github.com/jaswsinc/761812edb592733bc3a9

If that still doesn't do the trick, you can try adding this line to your wp-config.php file also.

define( 'DIEONDBERROR', true );

[thienhaxanh2405]

I updated installer.php. It doesn't do the trick :)
And, here it is, message after added define( 'DIEONDBERROR', true );

[jaswrks]

@thienhaxanh2405 Thank you very much. Unfortunately, that doesn't tell us why the DB table creation failed; i.e., the output only shows the SQL that was attempted, which is working in our tests. So what I was looking for is why this is failing on your side exactly, so that we can try to work around a potential compatibility issue that may exist.

@PanNovak Is it possible for you to run the same experiment please?
See: #260 (comment)

It may also help to review your MySQL error log, if you have access to it.

Unknown storage engine 'InnoDB' -> this is weird, i don't use MySql5 InnoDB, I use just MySql5.

I can't find/access db logs now, we'll try to find them later. I've got to go now. :-)

WordPress database error: [Unknown storage engine 'InnoDB']

Thank you. So it looks like you may have a problem with the MySQL installation on that server. The InnoDB storage engine for MySQL has been available since at least MySQL v5.1, and as of MySQL v5.5+, it became the default storage engine for MySQL installations, because it is better, which is also why Comment Mail uses the InnoDB storage engine.

My suggestion is that you contact your host to find out what is wrong with InnoDB storage engine on this server. Most likely there is an issue with the my.cnf file and they can probably correct this for you. WordPress itself will simply use the MyISAM storage engine, but many plugins (including Comment Mail) will prefer to use InnoDB if your version of MySQL supports it. Yours does, but it appears to be broken in some way.

If you find that your hosting company does not support InnoDB at all (that would be quite unusual), then please write back and we can provide you with instructions that will allow you to change the engine. You will sacrifice a little functionality in return for downgrading to an older storage engine, but we will get it working for you one way or the other.

[thienhaxanh2405]

@jaswsinc Look at my error message:

ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=1 ;

Something wrong here? InnoDB is my default, every table was set InnoDB but yours, The table _comment_mail_queue_event_log did create (I have no idea why only this table's created) and it's set MyISAM

[jaswrks]

@thienhaxanh2405 writes...

Something wrong here?

The issue that you're having seems to be a little bit different, and one reason for this is that your server is running MySQL 5.5.44, whereas @PanNovak is running 5.6.21. Whenever Comment Mail detects that you are running < 5.6, it must use the MyISAM engine instead, because Comment Mail DB tables use FULLTEXT indexes, which are not supported by the InnoDB engine until MySQL v5.6.

I haven't been able to pinpoint the exact problem on your server just yet. The last error report that you sent over just shows WordPress database error: []. It doesn't provide the underlying error message that may shed light on what is really going on.

If you have the ability to upgrade to MySQL 5.6 or higher, you might give that a shot. Otherwise, I'm afraid I'll need to see the underlying error message to know what steps to take next.

@thienhaxanh2405 writes...

Hmm. That's interesting, and it correlates with the fact that no error message is produced at all; i.e, it suggests there is not an error, and yet WordPress is reporting that there was an error.

Would it be possible for you to send over a private Dashboard login for this site for me? If so, please submit that here and I will take a closer look for you and run diagnostics. http://bit.ly/1WNqron

[PanNovak]

Yee--haw! I fixed Innodb and it works now, thank you! :-)

[thienhaxanh2405]

@jaswsinc how's your investigation?
On my local, running XAMPP v3.2.2

Apache/2.4.17 (Win32) OpenSSL/1.0.2d PHP/5.6.14
Database client version: libmysql - mysqlnd 5.0.11-dev - 20120503
PHP extension: mysqli Documentation
PHP version: 5.6.14

Everything is okay. But a strange thing, the table comment_mail_queue is set InnoDB.

[jaswrks]

Hmm. Well, InnoDB is better if your server supports it. There seems to be a conflict between what you're showing in that last output though (i.e., the MySQL version) and what WordPress is telling Comment Mail. In short, in order for Comment Mail to install InnoDB tables, you will need MySQL v5.6.4+.

See: https://github.com/websharks/comment-mail-pro/blob/000000-dev/src/includes/classes/UtilsDb.php#L157-L160

@thienhaxanh2405 Thank you. Was that test run with this alternate file that includes the additional error/debugging info as well? https://gist.github.com/jaswsinc/761812edb592733bc3a9

I ask again, because for some reason I'm not seeing any MySQL-specific error information in your last report like I did when @PanNovak ran tests, so it is hard to know for sure what the underlying cause is by just looking at the Exception itself.

For instance, in the other report here we noticed that MySQL complained and said:

WordPress database error: [Unknown storage engine 'InnoDB']

If you can find a way to produce that additional error info it might help. This alternate file that I posted before did the trick for @PanNovak. See: https://gist.github.com/jaswsinc/761812edb592733bc3a9

I see. Yes, strange. Can you please post a link that leads to a phpinfo(); output display for me? I'd like to see which MySQL extensions and library you're running with please.

[jaswrks]

@thienhaxanh2405 I think I may have found the issue. If you can try this patched copy of the file and report back that would be great :-) This copy excludes the debugging routines, and only tries to correct the problem that you reported.

[jaswrks]

@kristineds Here is an outline of what I did, in case you'd like to work on a more formal PR and review process, we can merge this into the official copy of the software.

• This line should be replaced with:

  if ($this->plugin->utils_db->wp->query($_sql) === false) { // Table creation failure?
  

• We should also do a search for other instances like this that might need to be updated also; i.e., search for !$this->plugin->utils_db->wp->query and review those. In most cases, we should be looking for a false return value, because a 0 return value will be falsy too, and yet not actually a failure. We need to look for false (boolean) explicitly to avoid this sort of problem.
