And more one method is to try entering in the "Editbox" field the command: /debug -p @debug
After this, a window named "@debug" should open to display debugging information. Next, test the scripts again on your network. After testing is complete copy from the "@debug" window and publish here all the lines or only those that may be relevant to your problem.
Explanation: In raw messages the text is displayed in its original unmodified form, along with the numeric value of the event, and in the debug information we can see almost everything that mIRC receives and sends, with the full data set on each line in extended format, depending on the IRCd settings.
The goal is to find the corresponding/similar line in some event or the reason that causes this line to be displayed: "BestGuest DE set by is connecting from Germany".
