1.13 is your problem. It uses a lot of RAM.
If you have 1.12 backups, use them.
You can't downgrade, as 1.13 has a new world system, so a world is kind of like automatically corrupted when you run it on 1.13.
If you don't have backups, here's some stuff you can do: By the logs I can see you have lots of plugins, try to remove some. Delete the world and load a new one in 1.12.2 or previous versions (only if it' a new server or if you don't care much about the world). Reset completely the server (you'll loose everything) and create it back in 1.12.2 or previous versions. Anything else that lowers server RAM usage should work. If you have many slots like 100 or 50, remove all you don't need. If you don't have enough slots (for example, 2 and you make 5 people enter), add more (I know these last two are very basic, but many people have problems due to them).
Also, Essentials logs an error, you should consider switching to EssentialsX as Odd said

I hope you find this useful, please make sure to reply saying wether it solved your problem or not

Thanks, this is much better than what I said, I didn't know this existed

I download backups frequently so if something happens I can go back to a previous state. You can do this by going to the worlds menu and pressing 'Download'.

I found a solution but it doesn't work well: I found a 1.12 backup save I had, so I uploaded it, but it didn't upload, as server crashed with 1.13 error: reuploaded it, same error. Downloaded to check: downloaded save was 300MB, while that backup was 196MB... I need help

I was able to fix this. Now my server runs properly in 1.12

I have tried 1.13.2, same thing. I have downloaded the world and tried to kill most entites, but it still uses around 1.4GB RAM (in local save)

Hello. My server overloads just when starting. I tried downloading the world, I checked it and there wasn't anything like a big explosion or similar which would crash the server, it's online, but when I join it it crashes ( I can't even load the map, I just get an out of time error). Here's the log: https://mclo.gs/psXaOVJ (see the ending for relevant information). It has happened since I updated to 1.13 (can't downgrade as I made it when it first rolled out and map upgraded)

I would really appreciate help

I guess. I tried with a backup but it doesn't work, I'll need to play in 1.13

And with the backup it doesn't load either

Hello. Recently I've had problems with my server, as I updated it to the newest version to test it. There was much internal lag, and later I noticed there wasn't OptiFine yet for the 1.13, so I downgraded it to 1.12. When I did this, the server couldn't start for errors mclo.gs couldn't detect, later I read this in the Minecraft forum:

<<The world save format has changed; worlds older than 1.13 cannot be opened with versions from 1.13 or later without permanently and irreversibly upgrading them to the new format, making it impossible to open them in earlier versions>>

Luckily I made a backup before upgrading, but I want you to be aware before upgrading: make a backup before or you won't be able to downgrade.
I know this isn't a question (and maybe it's in the wrong category) but I think this is important for all Aternos users who want to upgrade to 1.13.

I now know why:

<<The world save format has changed; worlds older than 1.13 cannot be opened with versions from 1.13 or later without permanently and irreversibly upgrading them to the new format, making it impossible to open them in earlier versions>>

Sorry for the console message being grey, you can copy it to Notepad in order to read it better

Hello. I recently updated my server to 1.13, but later downgraded it to 1.12. After the downgrade, the server stops while starting. I found this message in the console:

Ok, thank you

Hello, I think it would be a good idea to create a Discord server for Aternos
More information: discordapp.com

Fixed :D. I don't know what happened. It was like returning to 2015...

I had my server in 50 players (yes, that's a lot). Well, I noticed this new feature and I changed it. And I changed it again. And now only 2 people can enter. In my server I don't know if there it will be one or five people, that's a problem. Please, change this. More users will agree. I'm sure.

I've got an idea for the ads: If people have an adblocker on Aternos, just make people can't enter with it or only enter wathing a video ad every day, maybe it might be useful

Ok
