Critical error when trying to add a new form
I wanted to edit my forms today and found that if I try to add a new form I get a critical error. I tried as well on my other website that has WPDiscuz and found the same thing. I used the health check plugin to go into troubleshooting mode with only WPDiscuz activated and still got the error.
In the error log on my server
Wed May 18 01:14:05.248237 2022] [proxy_fcgi:error] [pid 24525:tid 139935772096256] [client 22.214.171.124:47634] AH01071: Got error 'PHP message: PHP Warning: Undefined variable $save_post_flag in .../public_htm............action()\n#5.../public_html/wp-admin/edit-form-advanced.php(271): register_and_do_post_meta_boxes()\n#6 ...', referer: /...wp-admin/edit.php?post_type=wpdiscuz_form
That's the only thing I could see related to wpdiscuz (I removed some of the identifying info here.
Any idea on how to fix this? I tried deleting and reinstalling the plugin without success. I don't want to delete all data.
We're going to check the issue. Please wait a bit. I'll get back to you know ASAP.
I responded via email a couple of days ago, but cannot see that any action has been taken. I'd really like to add a new form. Any idea on what might be causing this error?
