We had been experiencing
500 - Internal Server Errors on some of our
Joomla 1.5, 1.6 and
1.7 sites while uploading extensions.
We had recently updated our hosting environment from Plesk 10.2 ->10.3.1. In addition to the 10.3.1 updates run with the Plesk Panel, we also ran updates for our VPS container via the Power Panel.
After the updates we had issues with extension uploading. All our sites are run with the
FastCGI module by default with our hosting plans.
The updates included an update for the
psa-mod_fcgid (Alternative FastCGI Module for Apache 2). The
psa-mod-fcgid update is now version
2.3.6.Apache Error log showed an error of -> mod_fcgid: HTTP request length 203991 (so far) exceeds MaxRequestLen (200000), referer: %yourdomain%/index.php?option=com_installer.
Changes in
2.3.6 FCGI change the
FcgidMaxRequestLen directive from the previous 1GB to 131072 bytes. Thus, any uploads larger than 131072 bytes will return the 500 error.
An edit of /etc/httpd/conf.d/fcgid.conf is required to return the original default value.
Add or change the FcgidMaxRequestLen value.
From:Code:
FcgidMaxRequestLen 131072
To (for 1GB):Code:
FcgidMaxRequestLen 1073741824
Restart Apacheservice httpd restart
Fixed
This issue will be applicable for any hosting environment or website backend using FastCGI 2.3.6
