Gtmetrix waterfall entries

Hello,

I can look into this for you. Can you first make sure you update the plugin to the latest version, then go to the Shift8 CDN settings page, click “support” tab and click “copy info below to clipboard”.

Then you can paste the debug info here, or if you prefer email to [email protected].

Once I have all debug information, I’ll take a look into what can be done.

Thanks!

Hi that’s great

Only thing is when I click the support tab there’s only a link to the support page here , no “copy info to clipboard” option ?

Yes, we pushed out an update to the plugin earlier today so if you go to the wordpress plugin update page, please proceed to update the plugin to the latest version. Then in the support tab, there should be the things I described to do.

Thanks, got it, and got the info, about to email it to you. Thank you so much for your help with this.

No worries, leave this with me. It might take a bit of time as these types of things are really tricky as most of the problems lie with a conflict with another plugin.

Hi,

Yes, I’ve a couple of other issues currently, and plugin conflict has been mentioned with those too. Shortpixel thinks Shift8 is a conflict for theirs not working. Hummingbird thinks Shortpixel is a conflict. So difficult to know where to begin.

Appreciate any help you can give, because image delivery is key to my site and since I put shift8 on they are so much quicker.

Well all this plugin does is rewrite URLs with static assets to use the CDN url.

Technically you can use either another plugin (i.e. wp rocket) or use .htaccess / nginx rewrites to convert static asset urls to use the cdn , so :

https://www.yoursite.com/wp-content/themes/yourtheme/style.css

becomes :

https://<YOUR-CDN-PREFIX>.wpcdn.shift8cdn.com/wp-content/themes/yourtheme/style.css

If the Shift8 plugin is breaking, all that is breaking is the rewrites of the URLs. The actual CDN will always work , you just have to tell your site to rewrite those urls.

In a future version, I could offer to generate nginx or apache rules that you can just add to your htaccess file. I would have to test those types of things as well. I dont imagine the plugin conflict issue will ever go away as its almost impossible to test conflicts with all wordpress plugins but I’ll try my best!

I would really appreciate any help you can give on this, I don’t think Shift8 is causing problems with other plugins, just relaying what was said really. It is a nightmare trying to work out which is conflicting with shift8 though to get those long blocking times on the gtmetrix waterfall.

All the .htaccess entries are correct and the images are being delivered via the CDN. Could there be a conflict with commonwp (a CDN that grabs wordpress standard files from a CDN) or that I need any cloudflare rules ?

Just a thought.

Hello,

Actually are you able to run the following test for me , as it would save a significant amount of time :

1. Disable all plugins except Shift8 CDN
2. Re-enable each plugin , one-by-one and verify each time you enable if the problem arises.
3. Once you have identified the specific plugin , let me know here and I can look further.

Thanks!

Ok, I will, but it’ll take some time to get back to you.
