You're lucky, Rosie! I did! It scared me when, for a minute or so, I got the infamous 500 Internal Server Error!... Yikes!... that's the scariest one for me, because it almost never shows up on the system logs, so I usually have no clue what's wrong... this time, however, it was a simple fix!

I guess that the pandemic gives the opportunity for all these kind developers to stay at their comfy homes behind their keyboards, and so they have lots of spare time to update their code...
