Stylesheet got not loaded and image slider disappeared

[synologix]

Hello,

i have a small problem on my Joomla 3.1.1 with latest Phoca Guestbook.

symtoms:
- It loads but looks like it´s loosing the stylesheet.. (no tabs on the top only a unsorted list)
- another thing is.. i have a image slider on the page and this got loaded on all pages exept the guestbook page.

my test site url is: 35.messezimmer-in-nuernberg.de

- it makes no difference i use my template "jYaml" or the preinstalled "beez3" (both problems on beez3 to)
- i have switched off mootools and jquery in all possible modules for preventing conflicts with the guestbook

any ideas how to fix this ?

Best Regards

Hannes

Hi, if the template is not a bootstrap template, some features like tabs are not working (e.g. tabs) - I will try to add some specific style for non bootstrap templates in next version to prevent from such problems.

Image slideer - check if there is some error message on your site (javascript error message) - maybe there is some conflict

EDIT:
I see this error message there:
