Thanks @pfaffman this is reassuring! I sort of thought that was probably the case, but since I’m having such problems with this import I have been doubting my knowledge and skills at every level!
Thanks for the tips, everything is appreciated @pfaffman - this is a long-delayed reattempt at the same forum I was working on last year. It’s a pro-bono job but I might get you involved again if you have time.
It’s a very old SMF2 forum which has attachments in the two forms:
<id>_<File_name_NO_CLEAR-case_rules_jpg>_<32charprobablyMD5hash0fsom4thing><id>_<40charprobablySHA1hash0fsom4thing>
I’m still trying to work out if there’s a pattern to the failures.
