If you remove LargeFluidTank does it still crash?

He means the folder containing the mods, it's on your desktop, not where the mods are actually supposed to go per the installation setup.

Read the Pixelmon website, you're not using the version of forge they say to use. Always read the instructions!

I do not believe 1.10.2 is supported any longer. That being said, looks like googly eyes is causing the problem. Try removing that and see if it helps, however, be warned future topics related to a version as old as 1.10.2 will potentially be locked by moderators.

If you are behind a firewall/router, you will likely need to forward the port to the computer running the minecraft server. Instructions for doing this vary from router to router, consult the manufacturers website or instructions for how to do it.

Make sure you only download mods from curseforge or directly from the mod authors website, do not use sites like 9minecraft. See https://stopmodreposts.org/ for more info. Any mods you might have downloaded anywhere else I would delete and redownload. (some of your mod filenames suggest you downloaded them from elsewhere)

A good rule of thumb, any website that throws a random number in front of a product name is probably shifty

What folder are you choosing as your workspace when you load into eclipse? Just curious, since I see that message about overlapping.

Not sure if it's related to your issue, but I would remove optifine from the server, since optifine is a client mod for increasing performance. After that, I see an error about bloodmagic, maybe try updating that and/or forge to the most current/recommended versions.

If you need help finding logs, the EAQ has info on finding them:

It looks like perhaps you are trying to use a 1.14.4 version of the replaymod with 1.13.2 Remove the mod, update it, or install forge for 1.14.4 and update your installation, and see if that helps.

What happens if you try more than 5 mods? Please post logs to show us what happens.

The only mod I see referenced in this log is speedy hoppers, if you remove that mod, does it still crash? also, where did you download mods from? I would only download them from Curseforge, if you downloaded them from shady websites like 9minecraft, delete them immediately and redownload them from curseforge. See https://stopmodreposts.org/ for more information on why this is bad. If you got your mods from a legit source, and it still crashes after removing speedy hoppers, post the new crash.

Make sure you read the instructions for mods you use, I'm pretty sure you're not using the correct forge version as stated on the pixelmon website.

Moderators will tell you the same thing. And if you've got the same problem, then post your screenshot of the updated launcher as DaemonUmbra asked the OP.

You should create your own topic, and post logs/screenshots so people can attempt to accurately diagnose the issue.

Update to the most recent launcher

I believe Fluids are still being worked on, but when they're working I believe there's going to be a recommended build for 1.14.4.

You probably need to create a new installation in the launcher ("Installations" at the top next to where it says "Play"), and choose the version of forge you just installed. Make sure when you're picking the game version, you check the bottom of the list, that's where forge usually shows up.

Fairly sure it's 1.12.2+ for support, current version (1.14.4) and previous (stable) version, 1.12.2. You might get help for 1.11.x, but for certain nothing below that.

What launcher are you using?

Any mod you did not download from curseforge, you should delete and go redownload from curseforge. If you forget which ones, honestly I'd go do all of them.

If you know which mod it is, you should be able to just delete it from your mods folder. I would also make sure all mods downloaded from sketchy websites have been removed, who knows what's been packed into them or how out of date they are.

Post new logs for the new crash please
