I had to back out of WP 6.8 to WP 6.7.2 AND use the previous version of DM for my files not to be blocked after uploading, i.e., the load failed. I had auto-update set for both and it created a huge headache. Maybe I am the only one to have a problem but, nonetheless, it happened. To be honest, since I had to make a number of permutations of the various software to figure out the culprit(s) I am not 100% sure but I THINK that the new version of DM also had a problem with WP 6.7.2 as well. I won’t swear to it but I believe that is the case. Only when I restored the previous version of DM did the problem go away.
