Hi All,
Microsoft's latest version of Internet Explorer has changed its User Agent string, which causes a lot of existing JavaScript code to misidentify it as Firefox. Unfortunately, this breaks some functionality: the version of TinyMCE in the latest CMSB can't open popup dialogs in IE11, which prevents links from being created or edited, as well as preventing the use of the popup HTML source code editor. TinyMCE has fixed these issues in their latest release, so the simplest solution is upgrading TinyMCE.
We're going to fix this for the next CMSB release, but if you need a fix right away, just follow these steps, which are exactly like a standard CMS upgrade (but they only affect the cmsAdmin/3rdparty/tiny_mce directory):
- Create a database backup by clicking "Backup" under: Admin > General Settings > Database Backup.
- Download /cmsAdmin/ and everything under it to a backup folder on your computer. Don't modify or change your backup files.
- Download the attached file and unzip it.
- Upload the /cmsAdmin/ folder from the zip file and all files under it.
- Note: Only TinyMCE files will be overwritten.
IMPORTANT: IE11 users will also need to clear their cache for the changes to take effect. To do so, go to Tools (Gear Icon) > Internet Options > General > Delete..., make sure "Temporary Internet files and website files" is checked, and click Delete.
Let me know any questions, thanks!
All the best,
Chris
