Issue with current version of the plugin (pages are not displayed)

[asheenlevrai]

Hi :)

I am currently running DokuWiki Release 2018-04-22c "Greebo" from a Synology NAS. I have been using this setup for several years and everything usually works smoothly.

Recently I updated several plugins via the Extension Manager in the Admin Admin panel, including this plugin (Search Form Plugin).

Since this update, all pages that include {searchform} are no longer displayed (black screen) and tools on the right-hand toolbar are no longer available (buttons not displayed), e.g. edit page, previous version, manage subscriptions, ...

Disabling the plugin makes the pages to be displayed properly again (although obviously {searchform} is displayed rather than the search field). Re-installing the plugin doesn't fix anything (black screen).

I don't know what I should do. I don't know what other info could be relevant in this case.
Synology NAs runs the following packages: PHP7.2, PHP7.0, PHP5.6. I don't know if this is relevant.

Thank you very much in advance for your help, guidance and advice.
Best,

Could you check if the log contains messages?
Please see for more background https://www.dokuwiki.org/faq:blankpage

Thanks :)

I run from a Synology NAS so AFAIK I don't have access to /var (/var/log/...).
I guess I could if I'd SSH into it but I'm not familiar with that kind of things unfortunately (excuse my ignorance).

There are no error_log file anywhere either.

I'll look into showphperrors (it's not marked as compatible with Greebo) ASAP and report here if I manage to get any useful info from it.

Thanks again :)
Best,

ShowPhpErrors returns this:

Fatal error: Class 'dokuwiki\Extension\Event' not found in /volume1/web/dokuwiki/lib/plugins/searchform/syntax.php on line 121

You are using an older version of DokuWiki. The plugin is updated, and uses recent added features, sorry, at time of updating I did not realize it would break backward-compatibility.
Solution is updating your wiki (probably more and more plugins will have this challenge), or installing an older version of the plugin. e.g. you could try: https://github.com/Klap-in/dokuwiki-plugin-searchform/archive/609fb548c273382d9cc3a2b117aa3c0daf16c735.zip

Thank you :)

I am currently in the process of figuring out the best way to update our wiki and all its plugins.
Some are more problematic than others.

No changes needed.
