Hello,
I am truly lost trying to figure out what to do with this error. I would very much appreciate some help. I'm using Joomla 1.72 and installled JoomSEF 4.1.1. I have 3 errors I don't know how to handle. My site is on Bluehost.

PHP Warning: array_merge() [<a href='function.array-merge'>function.array-merge</a>]: Argument #2 is not an array in /home2/homeeduc/public_html/homeschoolguidancecounselor/components/com_sef/sef_ext/com_content.php on line 307

PHP Warning: array_merge() [<a href='function.array-merge'>function.array-merge</a>]: Argument #1 is not an array in /home2/homeeduc/public_html/homeschoolguidancecounselor/components/com_sef/sef_ext/com_content.php on line 315

PHP Warning: Attempt to assign property of non-object in /home2/homeeduc/public_html/homeschoolguidancecounselor/components/com_sef/sef.cache.php on line 510

This error has also occurred on line: 501, 509, 510, 502

Any guidance is much valued. Thank you! (homeschoolguidancecounselor.com)

Hello,

This means that there is some URL on your website that uses non-existent category ID. Anyway, we'll fix this not to throw a warning in next version of JoomSEF. Thank you for your report.

Thank you so much for your response. At least now I know what I'm looking for :) I was stymied.

Just thought I'd let others know that I think I stopped throwing this error. I cleaned out my cache (both joomla and joomsef) and rebuilt by menus, rebuilt my categories, check in articles. I made a few changes in categories and this may have caused the problems. I looks fixed now.

Also, I don't mind having the errors pop up from joomsef - it lets me know I have a problem I need to fix. Without that php warning, I might not have realized I needed to clean-up my mess.

Thanks!
