SOLVED "Optimize Website" (mod_deflate) refuses to enable (no error)

[jcwacky]

In cPanel > Optimize Website, I'm unable to enable the "Compress All Content" option.

Upon selecting it, and clicking "Update Settings", it says it was successful: "Website optimization preferences updated. Content compression is now enabled. Content compression is now enabled for all content."

But when I go back to the "Optimize Website" screen, it shows it's still disabled.

• It happens on all cPanel accounts on the server.
• I've reproduced the issue on a newly created cPanel account.
• The "Compress the specified MIME types" won't enable either.
• I've recently upgraded from EasyApache 3 to EasyApache 4.
• I've tried uninstalling and re-installing the mod_deflate module via EasyApache 4.
• It seems to successfully create a .htaccess file in the account root but doesn't add anything to it.
• If I delete the .htaccess file and try again, it still just creates a new empty .htaccess file.
• Some accounts already have it enabled, and the compression is working fine with these accounts.
• WHM 62.0 (build 16) - 11.62.0.16
• CLOUDLINUX 6.8 x86_64 kvm

Any ideas how I can resolve this?

Hello @jcwacky,

This is discussed on the following thread:

Compression not working

The temporary workaround is to add "zlib.output_compression = On" via "Editor Mode" in the INI Editor option in cPanel:

MultiPHP INI Editor for cPanel - Documentation - cPanel Documentation

Thank you.

Thanks, but I don't believe that's the same issue. For me, it won't insert the .htaccess content and despite saying it's enabled, when you go back, it says it's still disabled.

I did try that PHP INI update, but it hasn't resolved this issue.

Hello,

Do you notice any error messages in /usr/local/cpanel/logs/error_log when attempting to enable the option?

Thank you.

 

[jcwacky]

Nope, no errors appear in /usr/local/cpanel/logs/error_log, the only file that updates in that directory when attempting to enable Optimisation is access_log.

Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

Thank you.

I had buycpanel.com support get to the bottom of this. In case anyone else experiences the same issue, it seemed to be caused by file permissions of mod_pagespeed:

The issue here is that your file /etc/apache2/conf.modules.d/456_pagespeed.conf had incorrect file permissions causing the process to fail when it tried to read this file. The file permissions were set to 640, but since this process runs as the cPanel user, the file permissions need to be 644 like all the other configuration files in this directory.
