I started getting the same in the bio for one of my artists in the "NOW PLAYING" section after I changed the artist name by editing all the tags from "Namco" to "Namco Bandai". My artist images were also no longer loading, since I setup custom images to display rather than relying on the ones automatically found via the internet. I managed to fix the issue with the custom images, so they are working again by fixing the file names, but I'm still digging into why the artist bio is sill showing the "NewPP limit report" code.
There is a work around you can do to fix it by just manually entering whatever you want in the artist bio file [c:\Users\%username%\AppData\Local\MusicBee\InternalCache\ArtistData\Namco Bandai.bio.dat], then close and re-open MusicBee. If you want nothing to display for just this bio then you can put one blank space inside the file, since leaving the file completely empty will still bring back the "NewPP limit report" code. Alternatively you can also just rename the artist for each track inside the "tags" by changing a letter or adding an extra character, etc. I guess it's holding onto some cached file somewhere, but no idea where or what that is. Out of curiosity, what is the name of the artist in your MusicBee that has this problem? I wonder if it has to do with the way it's searching online rather than something locally on the computer.
Some troubleshooting I've done so far was completely deleting the "%LocalAppData%\MusicBee\" and "%AppData%\MusicBee\" folders, closing and re-opening MusicBee. I also searched through all the files in my %AppData% and %LocalAppData% folders along with my registry HKEY_LOCAL_MACHINE and HKEY_CURRENT_USER hives for reference to "Bandai", but found nothing useful for a proper fix. I guess next I can do a complete uninstall, make sure no old files for MusicBee are hanging around and reboot then re-install, but it would be nice to know what specifically is causing the "NewPP limit report" code to return.
Here is what I see in my artist bio:

Ok I see now where the biographies are coming from as per this release note via https://getmusicbee.com/forum/index.php?topic=27074.0
as a fallback wikipedia is used if last.fm artist biography fails - however wikipedia is not ideal as its not specifically focused on music/ artists and i am expecting there will be some cases of rubbish results
So yeah this is why "Namco Bandai" isn't found and it gives this "NewPP limit report" code error. When I updated the artist name in the "tags" to "Bandai Namco Entertainment" the info from Wikipedia (https://en.wikipedia.org/wiki/Bandai_Namco_Entertainment
) is displayed in the "NOW PLAYING" bio section. Of course you can also just turn off the panel where the biography appears from within "Arrange Panels..." if you don't want it to show.
Maybe you knew all this I stated here already or maybe I completely didn't understand the issue. How many artists are displaying this "NewPP limit report" code rather than a proper biography? If the text in the "artist" field within the "tags" isn't found on last.fm or Wikipedia, what would you propose as an alternative source of artists biographies? If needing a custom solution, I know it should be possible to at minimum to write a script that connects into some other source's API to grab an artists biography and use that to generate a custom biography for each artist you specify from an input file, or perhaps there is a way via a plugin that I'm not currently aware of as I'm also new to using MusicBee.
