Hi, anyone knows how fix the error:

PHP Warning: usort() [<a href='function.usort'>function.usort</a>]: Array was modified by the user comparison function in ........\libraries\joomla\utilities\arrayhelper.php on line 463

This error occurs after last update - 2.5.8 to 2.5.9

P.S. This error is in admin, the frontend runs normally....

Thanks all!

Hi goodpixel and welcome to OSTraining!

Can you go to Extensions > Extension Manager > Database and click Fix? Does that remove the error?

Also, what kind of server are you running the site on?

Hi Steve, I'm running Joomla in Linux server, with php 5.2
I can't access admin to make Database Fix.

I'll try some mods in line error of arrayhelper... soon I'll post again results
Thanks!!

I tried to make a modification in line 463, preceeding that with '@' and now I could access admin...

Now, lets go to database fix.

Thanks!

You're welcome, goodpixel. Glad that worked for you.
