@tranqdu
Please give more details about the issue. What do you mean “cannot create cache”
And create a report and share the ID. This can be done from: LSC => Toolbox => Reports => click on “send to litespeed”
@litetim
Website: https://wandleinwand.com
LiteSpeed Cache version: 7.1
Polylang version: 3.7.3
Web server: OpenLiteSpeed
When using Polylang with LiteSpeed Cache, the homepage (https://wandleinwand.com) is not being cached, while all other pages are cached normally.
Header response on homepage shows:
X-LiteSpeed-Cache: miss
or sometimes X-LiteSpeed-Cache: no-cache.
ID report : USMROWRZ
Please advise how to make the homepage cacheable when Polylang is configured to hide the language slug for the default language. It seems LiteSpeed Cache cannot detect the language context on wandleinwand.com (without a /de/ or /en/ in the URL), so it doesn’t create cache.
@tranqdu
Thank you for info provided.
My first thoughts are because of a plugin that disables cache on pages is used.
Let’s start debugging
1) In edit page make sure the page has NOT active Do not cache.
2) Links are not added here: https://docs.litespeedtech.com/lscache/lscwp/cache/#do-not-cache-uris
3) Enable Debug Log from https://docs.litespeedtech.com/lscache/lscwp/toolbox/#debug-log and set it to Advanced.
Open incognito page and visit homepage
Go back to LSC => Toolbox => Log view https://docs.litespeedtech.com/lscache/lscwp/toolbox/#log-view-tab and make sure Debug Log is selected.
Search for ——POST HTTP/1.1 (HTTPS) / (homepage request) and there should say why is not cached.
Example of what could be: ❌ forced no cache [reason] DONOTCACHEPAGE const.
This article will help with enabling debug: https://docs.litespeedtech.com/lscache/lscwp/troubleshoot/#turn-on-the-debug-log

Thank you about log but is not complete. 🙁
You can share full logs on: https://pastebin.ubuntu.com/ and paste the id only.
Thank you 🙂
@tranqdu please do not look for DONOTCACHEPAGE const
The logs are still trimmed.
Add this code in theme functions.php:
add_filter('litespeed_debug_show_max_lines', 'lsc_log_change_lines');
function lsc_log_change_lines(){return 10000; }
will allow to see more lines.

please try this:
debug log to ON
debug level to advance
debug include URI , add test
clean up existing log
then open page as https://wandleinwand.com/?test
and share the log again
@qtwrk
i did it your way. and here is the error log. is there really a way to fix this problem?

sorry for late response , it is indeed caused by that constant
please try add_filter( 'litespeed_const_DONOTCACHEPAGE', '__return_false' );
@qtwrk
Thanks. It’s working fine again.
@tranqdu that is a good fix from @qtwrk , your site will run good, but I would dig into why the constant is set.
But I would look further into why the constant DONOTCACHEPAGE is set:
– maybe page is removed from cache
– maybe a plugin add the constant for homepage OR in some conditions
If everything is ok, please set the topic Resolved. Thank you 🙂
