I've started getting this error when trying to Access Magento downloader, the rest of the site work:

The PDO extension is required for this adapter but the extension is not loaded

Been searching for a fix, but didn't find one...

My php.ini at the bottom has everything that is suggested, it worked before... I don't know what happened..

I had complier enabled, then wanted to install a new extension, so disabled the complier and this happened.

Deleted everything manually form Cache folder and nothing.

I have this in the php.ini, any ideas?



  • Does PDO show up in phpinfo()? Commented Nov 14, 2014 at 12:48

  • Have you re-run compilation, cleared cache etc etc? Commented Nov 14, 2014 at 12:50
  • How to correctly re-run compilation? Cache, cleared multiple times inside of magento and manually var/cache

Ok, found the Issue, downloader page was missing the PHP.ini.

Copied and pasted the same PHP.ini from the public_html directory to the downloader directory and it started working..

But I don't like this solution, because checked the default Magento instalation and php.ini is not present in the Downloader directory and I don't know, did I hack it or else... If someone has a clue, what could have happend, please post your answer.

Best wishes,

  • usually you have a central php.ini in your server config folder. But depending on your hoster, you are maybe not allowed to set these.
