I am experiecing endless problems trying to update to WPMUDEV Dashboard v4.0.4. This is really impacting on my business and causing me a lot of problems.
I am experiencing an error 500 - Internal Server Error. This appears after installing the plugin and then navigating back to the plugins list. I have now lost the ability to log into the admin function.
I have never had an error like this before with any other plugins.
Please advise ASAP.
