MyBB Community Forums

After you upgrade from 1.6.10 to 1.8.8 of the forum pages no longer match.
An example:
if I go to http://forum.openoikos.com/Forum-NanoCAD page (corresponding to a sub forums) from the link on Home page I see the message

Could not find the page forum.openoikos.com

No web page was found for the web address: http://forum.openoikos.com/forum-36.html


If I go to the same page by typing it directly to the URL tells me Invalid Forum.

Since it depends? What should I do?

Hi. 

1. Can You deactive all plugins, and deactive the tapatalk setting?

2. upload Again the files MyBB to your root.

3. Test again with default setting and files without modifications 

And Remember a Backups of your Database.

You'll need to re-apply the edits required for Google SEO (as well as upgrading the plugin to the newest version).
