Also another note is PHP 5.4.10 or higher likes to through this error as well ( Even on perfect PHP scripts). * Are you using a plugin for menus? * Thread Starter [tiaanswart](https://wordpress.org/support/users/tiaanswart/) * (@tiaanswart) * [13 years, 1 month ago](https://wordpress.org/support/topic/php-errors-11/#post-3677503) * Nope was busy developing a plugin for logging errors. Navigated to Appearance/ Menu and got the errors. My dev site is on IIS 7 so that’s prob why i got the errors. Will move the plugin over to an apache server and check the response. * [Justin](https://wordpress.org/support/users/jgwpk/) * (@jgwpk) * [13 years, 1 month ago](https://wordpress.org/support/topic/php-errors-11/#post-3677507) * I am still personally looking for a solution as well. I received the errors when using the latest version of PHP 5.4 and then downgraded back to 5.4.10 to fix the problem. I am not sure if this is something that WordPress developers need to convert or if it is a default setting in php that is different than the older versions (lazy and have not look into the changelog for PHP yet). * If you happen to run into a solution ( not a sever hack or change ) then please post back here. I would love to see what you come up with. * Thread Starter [tiaanswart](https://wordpress.org/support/users/tiaanswart/) * (@tiaanswart) * [13 years, 1 month ago](https://wordpress.org/support/topic/php-errors-11/#post-3677516) * Cool will do.

Going to upgrade it to 5.4 now and check what happens. * Thread Starter [tiaanswart](https://wordpress.org/support/users/tiaanswart/) * (@tiaanswart) * [13 years, 1 month ago](https://wordpress.org/support/topic/php-errors-11/#post-3677533) * Still get the same errors on 5.4… * Checked the change log on 5.4 and E_ALL was changed to include E_STRICT, I then added a check to see if the php version is lower than 5.4 to not redefine E_STRICT as it is already included in E_ALL. * Checked around the web and found this post on Stack Exchange: * [http://stackoverflow.com/questions/9734422/errors-when-trying-to-integrate-wordpress-on-my-existing-website](http://stackoverflow.com/questions/9734422/errors-when-trying-to-integrate-wordpress-on-my-existing-website) * more or less the same errors I get… * I checked in Apache and the same errors occur with 1 more occuring on Apache: * E_STRICT: is_a(): Deprecated.
