LS Cache incompability with WP 5.6, Avada theme 7.2

Hi,

May I know what is your webserver ?

you can check the http response header, if you don’t see header “x-litespeed-cache: hit” , then it means the page is not cached by LiteSpeed.

also please try with default setting first, I have seen white screen issue in certain cases that enables HTML minify and remove comments

Best regards,

LS cache creates random blank pages. It is so unstable. Deactivation and Uninstallation do not help. Only WordPress removal via FTP and reupload really helps.

Could you please investige the issue deeply?

Examples of LS cached pages which are blank.

Hi,

from my check , seems regenerate the cache will fix it

please try default setting first, see how it goes

I’ve seen this kind of issue with “HTML minify” option enabled

and also please do text search of your plugins/themes with keyword “ob_start”

these are 2 main reasons I have come across with such blank page issue

Best regards,

Hey,

1) Thanks for help. Turning HTML minification OFF solved the issue.

2) How am I supposed to do search “ob_start” in my plugins/themes? Shall I do it in wp-content folder on server or locally?

3) LS cache breaks the icons on the aformentioned page: https://rekinfinansow.pl/konto-przekorzystne-pekao/ – see lists – red and green li – what’s the solution for that?

4) is LS cache plugin itself or with extended paid service able to

a) eliminate render blocking css and js of theme on mobile devices
b) unused css and jss from loading
c) speed up contenful paint by 2 seconds?

Please take a look at the report: https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Frekinfinansow.pl%2F&tab=mobile

Hi,

2) if you have SSH access, then run grep -riF "ob_start" --include=\*.php /path/to/your/wp-content/plugins , then to /themes/theme-name

3) Could you please do me a screenshot ? I don’t see anything broken

4) unfortunately no , for render block , you can try load CSS async , but that comes with side-affect as FOUC , try CCSS as well then.

remove unused JS/CSS is on our to-do feature

I am seeing FCP as 1.8 seconds
