It's not working properly here as well
When i have the default files installed, users get many lines of the following error (the page is finally loading after a user submits a new thread though and all those lines with the error are disappearing):
Deprecated: Function split() is deprecated in /home/my_user/public_html/includes/functions_autotaggerfromcontentandtitle.php on line 85
When i try ozzy47's fix the page stuck and displays forever many lines with the following error:
Warning: str_split() expects parameter 2 to be long, string given in /home/my_user/public_html/includes/functions_autotaggerfromcontentandtitle.php on line 85
I have noticed a pattern though. Users get all those errors, only when they try to create a new thread on a section that new threads require validation before they are displayed. On the rest sections the plugin is working without any problems/errors!
