Hello everyone!
We are having troubles with CKEditor (4.3.1) on a PC of one of our customers. We are using CKEditor to edit the contens of our own CMS. On every other PC this CKEditor works well, but in this case the client is behind a proxy-server (unfortunetly we are not able to get more information about this proxy).
There were some problems in the past, especially when the user edited a lot of contents, where the editor showed old content instead of the updated.
Now the user reported a new issue:
When editing a content with tables and the user opens the table-properties the fields "cell" and "column" on the top left are empty. The values of the other fields are the values from a previous version of the content. Editing of this table-properties is not possible, because of the empty cell- and column field (error-message, that the fields are empty).
We compared the source-code of the content from the user behind the proxy with one of a fully working editor - they are exactly the same.
CKEditor ist showing some old stuff while the html-content is already the new one. Why is CKEditor doing this? Are there any functions in CKEditor that are destructed by a Proxy-Server? Has anyone any ideas how to solve this problem or hints that might help getting CKEditor to work in this special environment?
