Can anyone please tell me how to correct the following errors? They seemed to occur for no apparent reason... Thank you! Warning: main(/home/top1031e/public_html/project-forum/extensions/CategoryPageFirst/default.php) [function.main]: failed to open stream: No such file or directory in /home/top1031e/public_html/project-forum/conf/extensions.php on line 9 Warning: main(/home/top1031e/public_html/project-forum/extensions/CategoryPageFirst/default.php) [function.main]: failed to open stream: No such file or directory in /home/top1031e/public_html/project-forum/conf/extensions.php on line 9 Warning: main() [function.include]: Failed opening '/home/top1031e/public_html/project-forum/extensions/CategoryPageFirst/default.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/top1031e/public_html/project-forum/conf/extensions.php on line 9 Notice: unserialize() [function.unserialize]: Argument is not a string in /home/top1031e/public_html/project-forum/extensions/CategoryRoles/default.php on line 78

They probably occurred because you deleted an extension without turning it off first. To fix, edit your conf/extensions.php file and remove the one that looks something like <samp>include('extensions/CategoryPageFirst/default.php');</samp> If you still have that 'line 78' error, then do the same thing for CategoryRoles/default.php.

That worked! Thank you kindly...:-)
