I created a test instance, which worked fine. So, I created a backup of the live forum config file and then copied the test instance config file over to the live forum version. I then manually edited the live version file to correct the db username and password. I have not removed or changed anything else in the config file.
I followed your instructions (Cache and Editor) and switched the editor to TInyMCE. Then I attempted to start a post and got the following error message:
Fatal error: Uncaught --> Smarty: Unable to load template 'file:standard_text_editor_tinymce.tpl' <-- thrown in /var/www/html/ubbthreads/libs/smarty/sysplugins/smarty_internal_template.php on line 196
The tandard_text_editor_tinymce.tpl does not exist on the server. Nor does it exist in the downloaded copies of the zip files that I have. I have three separate copies of 8.0 on my laptop plus 7.5. and 7.4 and NONE of them have this file.

When I select SCEditor, I get this error message:
Fatal error: Uncaught Error: Undefined constant "FULL_URL" in /var/www/html/ubbthreads/libs/html.inc.php:2007 Stack trace: #0 /var/www/html/ubbthreads/scripts/newpost.inc.php(279): html->create_text_editor() #1 /var/www/html/ubbthreads/ubbthreads.php(286): page_newpost_run() #2 {main} thrown in /var/www/html/ubbthreads/libs/html.inc.php on line 2007
As you can see from the above, there is also no standard_text_editor_sceditor.tpl in any of the locations I checked.
