XF 1.1 Unable to create new forum node


Active member
I am no longer able to create a new forum node on my site, I just get a Mysqli statement execute error about the post_rules_url field. I can't think of anything I've installed since the last time I was able to do it with no problems. Any ideas?

This is what I get:

The following error occurred:

Mysqli statement execute error : Field 'post_rules_url' doesn't have a default value

There is no "post_rules_url" field in the default software. The NodesAsTabs addon is referenced in the error. You can try disabling that addon but that shouldn't be causing this. Try disabling any other addons you have installed to isolate the problem.

Just went and tried disabling add-ons one-by-one with no success. Tried disabling every add-on all at once and still can't create a new forum.

It didn't.This is what it came back with:

Potential Problems

  1. library/Ragtek/SLXT/Config.phpFile does not contain expected contents.
Showing 1 of 1 items

I disabled the Ragtek plugin and the file health check comes back clean but I still get the error when trying to create a forum. :mad:

I misread the error. It is an error returned by MySQL, not the datawriter.

This is a problem with the Merc_EnforcePostRules addon. Without going into the technical details... that addon has some problems. Since you are not currently using it (it is disabled) I suggest you simply uninstall it. That will remove the offending columns in the database which should fix the error.

If you choose to enable it again then you need to contact the author for an update. I see a few problems with that addon. xf_forum.post_rules_url and xf_forum.post_rules_overlay should have default values in the schema to avoid this error when the addon is disabled. And Merc_EnforcePostRules_ControllerAdmin_Forum::actionSave needs to call the parent function.
