  • Applies to:
  • Plesk for Linux/Unix

Symptoms

No web pages can be opened, they are loading continuously. 'ps' command shows only one 'httpd' process running:

 

#ps -ax | grep http | grep -v grep

8249 ?        R     18:57 /usr/sbin/httpd


Resolution

This problem usually occurs due to bad 'ioncube' PHP extension is loaded into PHP configuration.

You can find where the 'ionCube' module is loaded with the command:

#  grep extension  /etc/php.ini /etc/php.d/* | grep ioncube

etc/php.d/ioncube.ini:zend_extension=/usr/lib/php4/ioncube_loader_lin_4.3.so

Make sure that the extension is loaded only once (there is should be only one line in the output above).

If you left only one extension loading line, restarted Apache, but it still does not work, try to comment all the lines where 'ionCube' is loaded, restart Apache and check if it works. If yes, then you should download and install the latest 'ionCube' for your OS and PHP version from http://www.ioncube.com/loaders.php. Then restart Apache.
