it appears that you have one of two issues… 

first, try going to forum – options – global settings, and try disabling the css combined caching…

if that does not help, then your host is likely disallowing the php parsing of css files…  try switching your sp theme to the css only theme on forum – themes – theme list…

Thank you for your answer, but for the first part, the css caching is not enabled, parcontre I did not understand the second part!!

thank you

I installed the theme css only, but it still does not work

go the theme admin panel at forum – themes – theme list, and select the css only theme (that is the name of the theme) and see if that works…

If you do not have the css only theme, grab it here:

https://simple-press.com/download-themes/

also looks like you are caching the page with wassup… you cannot cache the forum page and must tell it to ignore the wp page the forum is on..

and you have some server permission problems… this is the css file on your server:

http://www.lespoiriers.fr/wp-content/sp-resources/forum-themes/css-only/styles/css-only.css?ver=3.5.1

try loading it up…  you will get an error which is why it is not displaying properly…

so you need to check the permissions of your sp-resources directory… make sure they are proper… also check the uid and gid of the directory (and all subdirs)…  permissions and uid/gid should match wp-content…

I installed the theme css only, but it still does not work

Current Theme : css-only 1.2.2 b

Thnx

problem is solved, in fact it is the type of permission problem that caused

thnx

Do you have a theme with the same color of my blog?

thnx

Good news. I have not seen your blog yet but have you looked at the various overlays that are available with the ‘defauyklt’ theme? Each one offers a different colour combination…

try the ‘in the money’ or ‘gin and tonic’ overlays within the default theme…

Could you let me know how did you solve the problem? I have this problem now too. Thanks

Boyang, did you see the reply to your topic???

this was resolved by correcting permissions or uid/gid of sp-resources folder in the server… I mentioned that on your post too, but other things to try first…
