Minecraft Forge Loader not working (I think)

[Danielrwood11]

I recently started a server on 1.12.1 (just for me and my friends) and used Minecraft Forge (the correct version) to start this. However, I downloaded FTB Util and FTB Lib from Curse and after I had downloaded them an error message comes up in the run-minecraft when I start the server and someone tries to connect: "[23:29:15] [Netty Server IO #2/INFO] [FML]: Disconnecting Player: This server requires FML/Forge to be installed. Contact your server admin for more details." Due to this, no-one can join my server, which is a major annoyance. I deleted the two mods and it still pops up with this error message along with saying that the mods aren't there which may cause problems. Despite what the error message says, earlier in the launch sequence it says: "[23:28:00] [Server thread/INFO] [FML]: Forge Mod Loader has successfully loaded 7 mods". This confuses me as it proves I have FML installed and it says when a player tries to connect that I don't. Is there any way to fix this, or if I want to keep my world will I have to make a fresh install, creating a new server and copying the world folder over? Sorry if this is very complicated or difficult to understand. Thank you so much for your help

Added some extra information, polished grammar.

Please post FML logs from both client and server.

Please will you explain to me how to get those?

Sorry.

Edit: I found this file (2017-08-12-7.log) in the logs folder, think it's either just a generic server log or maybe what you're looking for. 

I also found fml-server-latest.log, if that helps too. Still can't find my client logs though.

Edit 2: This time I went into .minecraft\logs, and found a log, it's probably for the game startup so probably useless. Sorry if it is, but it's 2017-08-12-7.log (the second one). So this and 3 are client side.

Edit 3: Apologies for all the edits. Going to add the latest log as well.

Edit 4: Found crash report that could be helpful (on the server side).

The client-side FML log is logs/fml-client-latest.log in your game directory.

The server logs are uneventful, the server crash report shows an issue with Perfectspawn.

I do not have a fml-client-lastest.log in any of my .minecraft folders. The closest thing I had was the latest.log that I put in previously. Sorry.

[Danielrwood11]

Ok, I will install the latest client version of Forge in the game directory, attempt to launch the server again and send you the log files when it is all done. Sorry for the inconvenience.

No, launching the server will not produce client logs.

I need the logs from the clients where the issue occurs.

Sorry, meant to say I'd join the server too.

[Danielrwood11]

I can't get Forge for 1.12.1 to install in my .minecraft folder. It says it has installed, but no new files appear. Thus it doesn't create any logs.

My apologies, ignore all of that please.

After starting Minecraft with Forge, it says that it found a problem with my Minecraft installation. I have mod sources which are duplicate within my system: MercuriusUpdater-1.12..jar and MercuriusUpdater-1.12.1.jar. It won't let me get past into Minecraft.

Like it says you have Mercurius in there for both 1.12 and 1.12.1. I advice you use separate game directories for separate versions.

Installing both versions was unintentional, to be perfectly honest. I only need 1.12.1. Could you tell me where to find the 1.12 version (or where it will probably be) so I can get rid of it?

 

[Danielrwood11]

All I have is mod_list.

[Danielrwood11]

Thank you! I have deleted 1.12 and am running Minecraft now and going to try to join the server so I can obtain the client logs.

[Danielrwood11]

_{I just deleted one incompatible mod and now the server's working. Thanks so much for all your help, definitely would not have been able to do this without you, thank you!}
