[SOLVED] Error 500 using template cache

[herr rilke]

hi there,

as soon as i setup caching for a template in PW backend i get error 500 in the frontend.

im using ProcessWire 3.0.239 on PHP 8.2

is there anything i need to do before using caching?

Hi,

I don't know but maybe template caching requests some module to be installed in web server, like URL rewriting.

Check your web server logs and you'll find the reason of this error.

mod_rewrite is in place but no entries in the log.file

What web server and OS do you use? Error 500 is a web server error, and errors are logged by default. The log file location depends on OS and web server, for example in xampp Windows with Apache, it's in xampp/apache/logs/error.log, in Debian it's in /var/log/apache2/error.log...

There must be something in either the error or exception log of ProcessWire itself.

thank you!
i found some entries in the PW exception log @wbmnfktr, not in apache's error.log!

variable @global-secondary-background is undefined in file /site/templates/RockPageBuilder/blocks/CallToAction/CallToAction.less in CallToAction.less on line 23, column 14 21| .uk-background-primary { 22| h3 { 23| color: @global-secondary-background !important; 24| } 25| .text { 26| color: white;
In /site/modules/Less/wikimedia/less.php/lib/Less/Tree/Variable.php line 50

i am going to fix this.

lessons learned: PW exception log was the right place to look for
