I’m getting this error on my site: Warning: preg_match(): Compilation failed: missing ) at offset 115 in /storage/content…………. (full message below)

I have read that it has something to do with the permalink structure. I think it first occurred when I change the permalink structure to something else but then I changed it back to the “post-name” option, but still the error is there.

Also, none of the category links from the start page is working, bar, nightclubs, spa, etc…

When I change permalink to “simple” the error message disappears but then the SEARCH function on the start page doesn’t work…and in FAQ you are guided to set it to “post-name” to solve that issue. So… I’m a but confused. Also I do want it to be set to post-name.

Anybody, any ideas?
