Umm... it's in my server's mod directory and it's working, but I see this answer elsewhere, about it being a client only mod. Try Fastcraft and fpsplus, PurpleTheChicken. Both of those are also working in my server. Try removing optifine from the server and putting those two in its place.

That's awesome.

Discovered the solution myself. Optifine HD U C1 lists itself as compatible with Forge version 10.13.4.1481 and I wasn't using that version. I didn't realize it wouldn't have compatibility with any version of Forge, since it's a recommended mod per the EAQ. As soon as I changed to Forge 1481, all mods suddenly worked. Hopefully this helps someone else in the future. Check other versions of Forge to see if they work and what's compatible.

If anyone can please help, it would be very appreciated. My friend bought Minecraft to play with me on a multiplayer server and we're both disappointed it's not working right now other than without mods (which are most of the point.) I'm using a newly set up 1.7.10 forge server. My friend was able to connect to the forge server running with an empty mods folder (though we had constant "can't keep up" errors, sometimes as long as 10,000ms.) Here's the list of mods I was ORIGINALLY trying to use: Adventure Backpack 2.0.4 Battlegear2-Bullseye 1.0.8.1 Better Dungeons 1.0 BiomesOPlenty 2.1.0.1387 BSpkrsCore 6.15 Dense Ores 1.6.2 Enchanting Plus 3.0.2 Extra Tinker's Construct 1.4.5 Fastcraft 1.21 Flat Signs 2.1.0.19 Fpsplus (latest for 1.7.10) Infinibows 1.3.0.20 Inventory Pets 1.3.2 Inventory Tweaks (latest for 1.7.10, someone said this is not a server mod, so removed from server) JABBA 1.2.1a Journey Map 5.1.0 Mantle 0.3.2 Mystcraft 0.12.3.00 Natura (latest for 1.7.10, don't have it at hand) Optifine HD Ultra C1 Project E (ie, Equivalent Exchange 2 for 1.7.10, latest) Tinker's Construct 1.8.7 Thaumcraft 4.2.3.5 Twilight Forest 2.3.7 I've added and removed different mods, trying to see which is the problem. I know for a fact it won't run with Optifine, EVEN BY ITSELF. Other than that, it seems to fail just randomly. The exact error I'm having is that the Forge server window comes up, everything loads, and as soon as it should finish loading, the window just disappears, as if it crashed unexpectedly. Here's the "latest.log" from the server when trying to run with all mods active: Biomes O Plenty works by itself, and I've had problems with other mods alone, not including Biomes O Plenty. Like, if I take Biomes O Plenty out and run it with all the other mods, generating a new world... it crashed again, just now as I tried it. Here's the latest.log for the run where it crashed without Biomes O Plenty: Saw Fastcraft mentioned in the last log, so removed it. Still same symptom of closing as soon as it seems like the server has fully loaded. I don't see any mods mentioned in this latest.log now, so I don't know where to proceed. Even assistance knowing what I should try next? Here's the latest.log with biomes o plenty and Fastcraft both removed: As a final test just now, I tried Optifine by itself. It too causes Forge to exit. Considering that in the EAQ itself is the recommendation: "Don't use MCPatcher! Use Optifine instead", I'd say that Optifine normally works, so what am I doing wrong? Here's the latest.log with ONLY optifine in the mods folder and a freshly emptied world folder.

I've already done that, as I mentioned in my first post. Optifine, by itself, causes Forge to exit. Considering that in the EAQ itself is the recommendation: "Don't use MCPatcher! Use Optifine instead", I'd say that Optifine normally works. Is there a better board here I could ask about this on? Here's the latest.log with ONLY optifine in the mods folder and a freshly emptied world folder.

I still have no idea what forum I should be posting this in, if this one is wrong. I gave you positive karma immediately on your first reply, because I was grateful for the assistance. Didn't expect to get slapped in the face.

The part where I had no idea what forum to use, where I was supposed to find a Biomes O Plenty forum, what I was supposed to say to them was the problem, or, PERHAPS MOST RELEVANTLY, the fact that it wasn't Biomes O Plenty that was the problem? I'd apologize upfront for my error in posting on the wrong forum. I thought you said it might be the right forum. I was just looking for someone who had more experience who could advise me about getting Forge up and running with some mods.

Saw Fastcraft mentioned in the last log, so removed it. Still same symptom of closing as soon as it seems like the server has fully loaded. I don't see any mods mentioned in this latest.log now, so I don't know where to proceed. Please, any help? Even assistance knowing what I should try to do instead of smiting me with bad karma for being a beginner?

It's definitely one (to several) of the mods, because it will run with certain mods (only a few) but not with most. Here's the "latest.log" from the server folder.
