On content management server, when you open the experience editor you notice that the ribbon menu icon is not appearing and sometimes the design is broken.
Not enough disk space on the server.
In my case, i have some PowerShell Scripts generating backup packages on the fly. Before launching, the script creates a backup of the items before modifying them (for rollback if needed).
The issue, i forgot to do the cleanup, so my disk space has been saturated.
- Ensure that you have enough space on you Sitecore server. Generally, the app data folder is among the most space consuming on the server so go to the folder app_data/package and delete unused .zip files.
- Go the path sitecore\shell\client\Sitecore\Speak\Ribbon\Assets\Sprites\Ribbon And remove all files. No worries, files will be re-generated by sitecore.
- Don’t forget to clear sitecore cache and another type of cahe if you have.
