Error: damaged content
When loading the page [WEBSITE URL] was violated the network protocol. This error can not be resolved.
I fixed it myself the JA login module needs an update, its redirect to a wrong file after Joomla is updated on 3.8.4. !
You can avoid it when you set up a redirect in JA Login module to your own landing page, but still it’s should not happen this way, i was happy when its redirect to the users page, please update the module! It was a shock of my life! Note for other customers: Joomla Core reinstallation does not work for fixing this issue!
I check it with many site installations before updating Joomla and after this, this error only appears after Joomla 3.8.4. update not on 3.8.3. and before.
