Database errors after activating

[florianbrinkmann]

Hi!

I activated the current Version 2.4.8 on a 4.7 WordPress multisite install and get the following 3 database errors:

DESCRIBE wp_mlp_languages;
Table 'db.wp_mlp_languages' doesn't exist

DESCRIBE wp_multilingual_linked;
Table 'db.wp_multilingual_linked' doesn't exist

DESCRIBE wp_mlp_site_relations;
Table 'db.wp_mlp_site_relations' doesn't exist

After reloading the page with the installed plugins I get the following errors:

ALTER TABLE wp_mlp_languages ADD KEY `` (`http_name`)
Incorrect index name ''

ALTER TABLE wp_multilingual_linked ADD KEY `` (`ml_blogid`,`ml_elementid`)
Incorrect index name ''

ALTER TABLE wp_mlp_site_relations ADD KEY `` (`site_1`,`site_2`)
Incorrect index name ''

Now I tried the code here from GitHub and with that I only get the first set of errors (Table doesn’t exist). After reloading the page, no further errors.

Hi!

Well, the first set of database errors is not (really) the fault of MultilingualPress, but rather due to dbDelta() being used to alter a table that does not yet exist, see this post, for example, or google for "dbdelta error describe" or so. :)
It's somewhat annoying, yes, but the result is like we want it to be: the tables have been created successfully.
And once the tables are there, dbDelta() won't trigger any errors anymore, so this is only the case when installing MultilingualPress (not on any subsequent re-activations).

The second set of errors has been introduced by the changed KEY (or INDEX) behavior of WordPress 4.6, I believe.
I definitely fixed this for master already (e.g., here), and I thought I also did so in a patch release for the 2.4 branch - which I obviously did not (yet). Sorry.

Expect a release for this by next week. :)

Cheers,
Thorsten

Hi Florian,

can you confirm the latest changes in the 2.4 branch work for you? You can also just grab the ZIP file.

Just let me know and a release will follow within the next days.

Thanks,
Thorsten
