I’m able to replicate it consistently now. Reset the settings for Topic/Reply Form, then walk through the initial steps:
In the “Topic/Reply Form” settings tab > #10, click to activate posting rules for both topics and replies.
In the Topics posting rules textarea I put “Test TOPIC rule”
In the Replies posting rules textarea I put “Test REPLY rule”
In Plugin Information, the values saved to the DB for that tab show:
s:16:"topic_rules_text";s:15:"Test TOPIC rule";
s:16:"reply_rules_text";s:15:"Test TOPIC rule";
Refresh the Topic/Reply Form and sure enough, it shows the duplicate “Test TOPIC rule” and “Test REPLY rule” is nowhere to be found.
Manually change the bad value for reply rules back to “Test REPLY rule”, and then it finally saves it properly.
If I reset the settings, I can consistently duplicate the issue. But once settings have been saved and then re-saved, it behaves properly.
Still digging to find the culprit, but at least it’s narrowed down to the initial saving of the options for that tab.
@metesey – Until this is officially fixed, my advice as a temporary work-around still stands: Try re-saving that tab, and maybe adjust values before re-saving.
