I've recently updated my jabber to 12.7.
After a reset of the jabber software I've noticed that the plugins were gone and the contact pictures were not loaded, also the photo cache folder was empty.
After some testing I saw that our jabber-config.xml had this header:
I've changed the version to 1.0
Which solved my problem after another reset and pc reboot. (Photo Cache folder was also filling again).
Any one else faced that problem? Strangely we faced no such problem with our previous version: 22.214.171.124004
