Are you using K2 V2.2 and JCE Component V1.5.7 and Plugin V1.5.6 with or without the K2 Adv Link?I have found an issue, that when GZIP Compression (Configuration > Setup) then K2 edit screens, for items and categories gets messed up.The JCE toollbar disappears and the K2 parameters menu on the right side has all parts fully expanded.I can not confirm if this is a JCE or K2 issue, but would like to get feedback from other users of K2 to gather information before submitting to JCE, if I can see it is related to that component.Thanks.K2Joom.com
