Hello, can you please do a SMF 1.1 Version of Alert Pro. Thank you

Sorry, but that is not going to happen anytime soon.

Greetings, @NIBOGO  .
I'm running a forum on 1.1.19 and I am interested in the Alert Pro mod. It has been a year since OP asked, so I wanted to ask if there any possibility of this still happening?

Sorry, but no, a port for 1.1.X is off the table.

Thanks for the reply.  How complicated is the mod?  I have had to manually install several mods on 1.1.x but I've never worked with the code of a SMF2 forum. Would this be quite a bit of work if I were wanting to try to adapt it to 1.1's code?

You would need to modify all queries and integrate the code added by integration hooks, you also need to do some modifications to the installation file.
