Another nerd question.
Apologies for continuing in the same thread, but the question is relevant to this topic.
This week, I made a change in TP Settings. I removed the collapse option for the Right Panel, so that it is shown as a default feature across all themes being used on our forum. After making the change, I found the recent topics block showing the same erratic behaviour. On checking TP-Subs, I found that it had reverted back to
'min_message_id' => $modSettings['maxMsgID'] - 35 * min($num_recent, 5),
So, the question is where is the old TP-Subs file being picked up from, if the latest edits are being lost ?
