Hello Rene,
I am sorry I've missed this thread.
May I know do you made some change in your current template file? It seems like when I'm in the middle of investigation, the template styling suddenly messed up on the frontend.
By the way, for your image caption issue it seems like the class="easyblog-image-caption" is missing from the image element in chrome while in firefox everything is working properly. I also able to replicate the issue locally. I will check with the designer of the team and see if they can come up with the fix.
