Hello, I have two questions the first question may have to do with the second question but I will start with the title of the post.

I have had this error pop up in the console saying Essentials Timer Error.
It started after I got a warning saying that essentials were generating an exception for task 4749 whatever that means.

I was wondering if that has to do with something on my end or coding in the plugin either way on to the next question.

I posted an error a day ago because this "terrible and buggy plugin" as someone posted on the topic said that GroupManagerX had problems, I was hoping if you could direct me to a plugin that works with Essentials, not buggy and fairly easy to set up or at the bare minimum that they keep it up to date.
I am unsure if that will fix my problem with essentials but I am willing to convert the permissions over to something that has better support.

This is the Task 4749 Error Log:

zPermissions is relatively easy to set up, although it's stable enough to basically not need any changes. PEX 1.x is also a reasonably popular plugin, but isn't really maintained anymore. Both are more stable and better maintained than GroupManager.

thank you for your reply.
