If you have questions about using mojoPortal, you can post them here.
You may want to first review our site administration documentation to see if your question is answered there.
When I use Google Chrome, in the image property box after click on Browse Server button, File Browser does not appear to me. File Browser box appear as empty box in Google chrome.
My chrome is updated to last version and the version of Mojoportal is 18.104.22.168.
This was a bug in CKeditor. If you upgrade to mojoPortal 22.214.171.124 it has a new version of CKeditor that is fixed.
Hope that helps,
How can I upgrade only CKeditor to new version without other part of Mojoportal?
If you don't want to upgrade mojoPortal I suggest just go into Site Settings and change the default editor to TinyMCE.
