PD breaks my Menu-CSS

[pickbaer]

Good evening,
I've changed my template to purity 3. On my testsite everything works fine. But if i click on Download, the whole menu turns into white. I've changed some settitngs , but i'm unable to locate the problem. It happens with firefox and chrome. After changing to another menupoint everything is displayed correctly.
Site is: https://test.bsvkalkar.de
Link to download: https://test.bsvkalkar.de/verein/download.html
Could you please help?
Many thanks in advance and greetings from germany,
Michael

Hi, unfortunately, with plg_jchoptimize plugin enabled, it is hard to see the loaded CSS on the site and hard to test the conflicts.

So you need to disable the plugin and try to disable step by step the CSS loaded to see in which file the conflict is

Hi Michael,

I think the conflict is bootstrap twice (template and PD) So: try following: Backend > Phocadownload > Styles (CSS) and de-active: bootstrap.min.css

Kind regards

Hi Michael,

that's fine.
Kind regards

OT: Wie schon Jan schrieb, ist es schwierig CSSen zu untersuchen, wenn plg_jchoptimize/cache .... aktiviert ist.
Man müsste dann noch Puritiy III untersuchen usw. usw. Da kann es halt, wenn mehrfach bootstrap.min.css geladen wird, zu Konflikten kommen.
