Safari Webp

Thrive Leads team is saying that the issue is created by Webp for the pop-up image:

“The issue is caused by the fact that you are using image file format .WebP”

They also provide instructions on how to exclude Thrive Leads:

“You can exclude Thrive Leads using query strings. You can add the query string *tve=true* in Do Not Cache Query Strings.

/wp-content/plugins/thrive-leads/(.*).js
/wp-content/plugins/thrive-leads/(.*).css
and add this in Do Not Cache URIs.”

Ok, I’ve done that and it works.

I tried to avoid this solution since it turns off Webp for the whole website and it is one more Litespeed Cache feature that I cannot use.

It might have something to do with their image paths. When I switched a website to https, I had to manually replace the path from http to https for their lightbox in the editor – SSL plugins that replaced everything else did not work for Thrive Leads.

Regarding Thrive Leads exclusions – usually when enabling Cache plugins (and especially minification/concatenation) for a website, there are just a couple of plugins that give me the most trouble. This is the case with Thrive Leads (+ Cube Portfolio + Max Mega Menu) for this particular website. Even though the plugins themselves do their job well, developer don’t give a second thought to putting together documentation on how to avoid this kind of issues, what to exclude and how. I’ve tried using the Blue Button Chrome extension to generate JS and CSS file lists prior to optimization, with mixed success.

So, long story short, I pointed this out to the Thrive Leads team and they obliged. Not sure if the exclusions are just for the editor mode?

Thanks.
