Hi @mcworks,
Could you please deactivate then delete the wpDiscuz and search/install it again?
The error says some files are damaged or don't exist. Also, make sure your server disk space is not full.
@tomson Thanks for the quick reply...
I have already deactivated, deleted and cleared errorlog log thrice now, no change.
Defaulted to Twenty19 theme and disabled all plugins no change..
This issue will be fixed in the next update. If you need to solve it asap, please open the wp-content/plugins/wpdiscuz/forms/wpdFormAttr/Row.php file, find the following line:
throw new Exception("Not whitelisted value detected");
and replace with this one:
throw new \Exception("Not whitelisted value detected");
In case you want to say thank you! 🙂
We'd really appreciate if you leave a good review on the plugin page.
This is the best way to say thank you to this project and the support team.
