Just utilizing the plugin to combine your CSS and js files should resolve this. The Optimize CSS Delivery feature was designed for something else.

I did a GTmetrix analysis on the page and I don’t see this issue. If you post the link to the report with the error I would be happy to take a look at it for you.

Yes that’s totally unacceptable. My sincere apologies. This is not always the case but a week of unusual circumstances. However, support is very much available.

A new version was recently released with a number of bug fixes. Otherwise, we would be happy to address your queries.

Thank you for your review and support.

Generally the permissions recommended for folders are 755 and for files 644. I suspect WordPress is applying those permissions during the update but it appears that on your server you need 775 for things to work normally so you would need to update the permissions after an update.

Ok but I’ve figured out why you were having that problem. You had actually subscribed to the JMSTARTER package. That’s the JCH Optimize Pro for Joomla!. I’ve updated your subscription to WPSTARTER, which is the JCH Optimize PRO for WordPress so you should be able to download it from the site now too.

Ok I’m glad to know it’s now resolved. You’re welcome.

The last version fixes a couple of bugs introduced by the previous version so you seem to have been affected by the bug too.

Sorry about that.

I’ve checked the site though and the pro download is working. You can’t download the pro version from the downloads page. You have to go to the My Account menu item when you’re logged in and you will see the Pro downloads on that page.

Let me know if you get through.

Check on this page https://www.ads-software.com/plugins/jch-optimize/developers/

Under ‘Other Versions’, click on Development Version to download and install and let me know if this fixes this issue for you.

Did you copy the codes as I have it? Check it again. Note the ‘return false;’ line.

You should note though that the plugin uses WordPress’s file system API to save cache files to the server. Apparently on your server the plugin can only access the file system using FTP so in order for the plugin to work on this server you will need to define the FTP_HOST, FTP_USER, and FTP_PASS values in your config file.

Edit the /wp-content/plugins/jch-optimize/jch-optimize.php file at about line 153 where you see this line:

$wp_filesystem = JchPlatformCache::getWpFileSystem();

Change that to:

try
{
        $wp_filesystem = JchPlatformCache::getWpFileSystem();
}
catch(Exception $e)
{
        return false;
}

Let me know if that fixes this error for you.

Ok thanks for the feedback. I’ve fixed this in development so the next version should resolve this issue.

This happens on some site I have found. The next version will fix this issue. It will be released within a week.

No problem. Happy to help.

The Sprite generator only works with background images. The documentation provides more details on this:
https://www.jch-optimize.net/documentation/sprite-generator.html

If these images are embedded in the HTML in img elements then you should try using the Lazy-load image feature instead.

I suspect the files that are triggering the alert are in the cache folder. These are actually the files that were downloaded and optimized from your website and cached by the plugin so it doesn’t have to perform the optimization on every request.

The contents are first serialized then encoded with MIME base64 to resolve some issues with saving and retrieving the data on different servers, which would make the codes even more innocuous in my opinion.

If I was using that plugin it would be interesting to hear what about these codes that are triggering this alert. This would be one way to validate that it’s actually doing what it’s supposed to be doing.
