Cannot access shop or admin page

[olivemarket]

Hello, after adding a new product to my store, I encountered an error. I am no longer able to access either my store page or even the admin market to undo my change.

The error given is:

There has been an error processing your request Error log record number: 1441239361194

Warning: fopen(/var/www/var/cache//mage-tags/mage---e69_MAGE): failed to open stream: Permission denied in /var/www/vendor/colinmollenhour/cache-backend-file/File.php on line 646

Hi @olivemarket 

It looks like some permission issue.

Give the below permission to var/ folder from magento root folder.

sudo chmod -R 0777 var/ pub/ generated/

You can also found the error in the var/report folder. There will be a document file with the name of 1441239361194.

I hope it will help you!
