Extension is not working at all, I think it should be High priority

Fz-29 subscribed.Apr 16 2017, 7:33 PM

@Reception123 how to reproduce this error?

Reception123 added a comment.Apr 16 2017, 7:34 PM

@Fz-29 I don't know but we're running on stable 1.28 and it's not working.

Yaron_Koren subscribed.Apr 17 2017, 1:47 AM

What version of Page Forms are you running?

Reception123 added a comment.Apr 17 2017, 5:33 AM

As I said the stable REL1_28 version.

Aklapper added a comment.Apr 17 2017, 10:12 AM

@Reception123: For future reference, please follow https://mediawiki.org/wiki/How_to_report_a_bug and always include exact MediaWiki and extension version information.
Also see https://phabricator.miraheze.org/T1489 where you already reported this problem.

I know, but I figured since it is not a local problem it must be dealt by upstream. Is any more information necessary here? I have provided the version, the error and the error message.

Reception123 added a comment.Apr 17 2017, 10:15 AM

@Aklapper Do you know what the issue is? Can it be fixed/maybe backported to 1.28 as there's still a few months still stable and as the extension doesn't work at all it should be IMO.

Yaron_Koren added a comment.Apr 17 2017, 12:22 PM

@Reception123 - you should generally not use the "REL" versions of Page Forms - they are not an official release, and just represent a random snapshot in time. Using the latest version is probably a better bet. Though I don't know if that's the issue here.

This also may be something specific to the combination of Flow and Page Forms.

What were you doing when you got this error - calling update.php?

Reception123 added a comment.Apr 17 2017, 2:14 PM

@Yaron_Koren We are a wiki farm and we use the stable version of extensions. I got this error after simply installing the extension. I will try it on a wiki without flow.

Reception123 added a comment.Apr 17 2017, 2:35 PM

Unfortunately there are some problems with testing this. If you want you can change this task to just be a interaction with another extension problem.

Yaron_Koren added a comment.Apr 17 2017, 3:21 PM

Okay - well, "REL1_28" is not the stable version of Page Forms; it could contain any number of bugs. The stable version is 4.1.

Barring any further information, I would have to guess that is an issue with Page Forms + Flow... I haven't heard of anyone else using them together, so maybe that's it.

I will try the master version and see if there are still errors.

Reception123 added a comment.Apr 17 2017, 3:43 PM

Unfortunately the master branch is the same.

Oh well.

An instance of MW 1.31.5 running on PHP 7.3.16-1+ubuntu18.04.1+deb.sury.org+1 (apache2handler) has just started to exhibit this exception after I upgraded from PF 4.7 to 4.8.

The exception occures in one of two wikis sharing the same codebase. The affected wiki has Flow enabled (and flawed!)

Disabling Flow resolves the issue. So does downgrading to PageForms 4.7

Yaron_Koren lowered the priority of this task from High to Low.Apr 26 2023, 12:22 AM

I'm changing this to low priority, only because Flow/StructuredDiscussions seems to be on the way out.
