The config file, yes, and it also depends on what level of the mining you are at. If you are at a SUPER high level, then its supposed to be 25, and if you are level 0-30 or something, then obviously use the config.
Try installing one by one of the mods, and then when suddenly you add just one of them and it crashes, there you have the culprit! Thats what i do everytime. It does seem like you have a problem with the server too....
did you install forge AND modloader? Because then it wont work, because they dont have a compatibility. Just install forge will be fine ...otherwise...retry the download and please tell me how you downloaded it.
What does your mob trap looks like? You should follow direwolf20s mob trap, that works VERY well. Make 4 sides, fill with water, then add a platform. Make the mobs that fall into water fall down a hole and die. Then make a form of getting the items
Are you on hard? More monsters spawn there, and also what biome, or where are you in-game?
1. Download MCEdit 2. Select the whole world area of the map 3. Click Export...Rename it into the file you want and then save it somewhere you want it to be. 4. Go to the 2nd world, click import, select the file you exported and click where you want it to be.
