Switching to Bootstrap3 theme breakes the page; error message "Problem with DOCU_INC directory."

[neki]

Hi,

I have just installed Dokuwiki. After I changed config to make my account an admin, I have installed bootstrap3 theme sucessfully. However, once I switched to bootstrap3 theme, page is "broken" and there is this notion with red background on the top of the page: "Problem with DOCU_INC directory. Please check your Dokuwiki installation directory!"

Any suggestions? Thank you.
Martin

Do you see any 404 errors on the browser side or errors on the app/server side which might give some hints?

@nebulon No 404 error on the browser side - it just seems as a page with wrong css (content is there but formatting is wrong). In the log, there are following warnings/errors.

@neki looks like it misses some files. Were there maybe any further install steps required? I have never attempted to install a theme in Dokuwiki...

[neki]

@nebulon I tried both extension manager and manual install from zip file with the same result. There are no other steps. Just to be sure, I have installed another theme and it worked fine.

@neki then you may have to contact the upstream developers about this. If you do, maybe you can paste the link to the upstream issue here for reference.

@nebulon I would do that but I don't know how. Is there any guide for this? Thank you.

@neki it seems for this particular template/theme the issue tracker is at https://github.com/giterlizzi/dokuwiki-template-bootstrap3/issues
