As reported yesterday, I enabled the Accelerated Mobile Pages (AMP) version of my Blog again. And as I mentioned in the updated post: I found some issues! This issues are solved and the Accelerated Mobile Pages (AMP) variant should work fine now.
During the fix, I decided to update the permalink structure of my blog: The URLs should be much nicer now! They will not contain the Article number anymore.
But due to the nature of changing the permalink structure of WordPress, there might be some other issues (mostly 404 – Page not found). Sorry about that that!
