No problem.

Generally you should disable any page cache plugin while configuring JCH Optimize. This is just so you can see the changes to the site immediately when you’re changing the settings. After you’re done, flush your cache and re-enable the cache plugin.

If you’re referring to Optimize CSS Delivery to eliminate CSS render-blocking then this article should help you:

Thank you for your continued patronage.

The plugin has been successfully tested on 4.4.1 and works ok. I fear it may be something specific to your site or server that’s causing the problem. The error message you posted won’t affect the operation of the plugin, that only affects the multi-select lists in the plugin admin for the Exclude Options.

Can you provide more information as to what is not working exactly? Is it that the plugin doesn’t seem to be running? Have you checked the source of the page to confirm?

Maybe this article will help:

Ok good to know that resolved this issue.

Thanks a lot @andrew for the corrective action. Thanks @kubik-rubik for drawing attention to the fake reviews.

Thanks for the feedback. We intend to make it better and better.

Thanks Victor. Yes someone’s obviously trying to vilify the plugin because they’re all evidently from the same person, apparently with some ulterior motive. I don’t worry about it though, I just let the performance of the plugin speaks for itself.

Check your Download ID and see if it’s correct.

I have tested it with WP Super Cache and it works ok but I’ll check it again.

Did you flush your cache, including browser cache after making the changes?

Ok I’m glad it worked and you like it.

Thanks for the feedback.

Ok if you want a pre-release version to try out in the meantime, submit a ticket on the site and I’ll send you a copy. Would appreciate any feedback.

We’re trying to finish all development and testing by the end of the month for release.

Google fonts alone shouldn’t decrease your score by 20% though. In my opinion it’s a small issue. Are you sure you’re not missing something else?

Google font files are currently ignored by the plugin because these files will serve the font type based on the browser that accesses it. If JCH Optimize caches these files then the font will show incorrectly in some browsers.

The next version will have support for Google fonts by caching the appropriate file for the respective browser so it serves the cache intelligently to display the correct font in each browser.

This should be released by the end of this month.

As you correctly concluded, this is a file permission issue on the server so I would recommend contacting the host. Ask what permissions do you need to set for directories so PHP can write to them.

On some websites I think you need to write files via FTP but this functionality is not in the plugin. I could consider it for future versions if this is the only way it can work for some persons.

If you’re still having trouble after speaking with the host I would recommend submitting a support ticket on the website so I can look at it more closely for you.
