After import i’ve some problems with tags like [font= ‘Open Sans’, serif;] [color] or [align=justify] [/align] Mybb ok with these tags but Discourse not supported. How can i delete these tags from the posts, but only tags, not the content? Can it be done with rebake?
Ideally the importer would be modified to remove this formatting. Failing that, you might try Replace a string in all posts. If there are lots of different fonts or alignment tasks, it’ll be tedious.
