Should I worry about this?

JoleneP

This error is appearing when I try to clear the cache.
And at least one member has sent me a message about this when they posted.

JoleneP you have to check your logs. We cannot diagnose your issues blindly.

I was hoping it was a common occurrence and I wouldn't have to get intimate with the problem.

In hindsight, I really should have gone to hairdresser school and then the only technology I would need is a pair of scissors.

JoleneP the error message is common as it states that there was an issue somewhere. But we cannot diagnose the error message without knowing that the error is. You have 2 issues at minimum and hopefully not more based on the fact that 1) you have a potential permissions issue with clearing cache and 2) your users are having errors populate as well.

I don't want to post the entire log file because it's huge.
But so far here's what jumps out at me :

JoleneP error logs are broken up in time stamps with most recent on the bottom. You should send relevant errors in whole and place them in the code tag. This allows it to be condensed and scrollable here while we address all the issues together.
As far as the error you sent, it says you have proc_open() disabled. This likely explains why you're having email issues to begin with. You need to enable this on your server for the error log to go away and maybe your emails can send. However, I always advise using Mailgun or another SMTP provider for email reputation so nothing goes to spam.

My friend... Thank you for making certain that I understand the value of having email working. 😃

Ok, back to the 'Opps! Something went wrong' error.

This is the bottom part of my log file. Unless I need new glasses or I'm missing something... , I'm not seeing anything different.

JoleneP I've updated your post with the proper code layout. Please use this as I've mentioned this earlier.

Edit, a failed email is hanging up on your server because of the error mentioned in my other reply.

KBExit

JoleneP My friend... Thank you for making certain that I understand the value of having email working. 😃
Ok, back to the 'Opps! Something went wrong' error.

Maybe you misunderstood what I said... Your error logs are pointing at your emails being the fault of your issues... If you read the error log line by line, you'll see mail is mentioned every time. Which all ties back to: proc_open() if you look at the very first line where the date is mentioned.

Thank you for the help again. I would have thanked you sooner but I got busy with other stuf.

Rest assured I'm addressing the mail problem.
