Well, there can be several issues which result in the Joomla article save / apply button not working and saving/ applying changes to the joomla article, such as:
- there are some files missing, maybe due to error while uploading the files to the server
- there is some plugin that is disabled, such as the editor plugins
- other issues
So how to fix it then? the solution lies in several steps, follow them in sequence if the problem of the joomla article save button not working is not fixed:
1. Update Joomla! to latest version
Well, even if you don’t face this issue(that articles not being saved due to buttons not working) or any other issue in Joomla!, you should always keep the joomla version to the latest one updated due to many reasons.
However updating also solves the issue of joomla Save/apply button not working to save the article issue too mostly.
2. Make sure Editor Plugins are enabled
Goto joomla plugin manager and check if the editor plugins are enabled and working as normal.
3. Rule out any interference
If the save/apply button for the Joomla article stopped working recently after you installed any extension to joomla (modules/components/plugins) then try by disabling/uninstalling that extension (modules/components/plugins) and see if this solves the issue, in case if that extension was causing interference with the joomla articles save/apply button and thus making Joomla unable to save the articles.
The issue of the Joomla articles not being saved due to the inability of the save/apply button to work properly should be fixed by the application of the above two methods (the first case only in most cases)
