ZendExtensionManager.so: cannot open shared object file

Posted by: admin November 30, 2017 Leave a comment


I just updated my apache installation (via easyapache in cpanel) so that mod_deflate would be enabled and I also updated PHP from 5.3 to 5.4 in the process. After doing this I found a redirect loop was happening on a WordPress site on the server.

After banging my head against a wall I opened a question on WordPress Answers: https://wordpress.stackexchange.com/questions/123037/redirect-loop-in-wp-admin – the answers led to the conclusion that the error resulted from the php version update.

I found the following error appears in my apache error log every time I try accessing the page with the redirect loop:

[Tue Nov 12 15:46:40 2013] [error] [client] Failed loading /usr/local/Zend/lib/ZendExtensionManager.so: /usr/local/Zend/lib/ZendExtensionManager.so: cannot open shared object file: No such file or directory
[Tue Nov 12 15:46:40 2013] [error] [client] Premature end of script headers: index.php

That error iterates itself several times each time I attempt to access the /wp-admin/ url.

I’ve checked and there is no folder /usr/local/Zend/ – is that bad? If so how can I go about fixing this issue.

Any help is greatly appreciated!


Ultimately the only answer I found was to revert the PHP version back to 5.3 – issue solved for now.
