Can someone please advise me on the following problem
Here is a link to a video showing what is happening https://vimeo.com/228143296
I strongly believe this is a permissions problem
In video clip one I do the following steps
1. In terminal I type in command - php bin/magento setup:upgrade
This brings up a warning message in red
(Permission denied in /var/www/html/top-property-store/vendor/colinmollenhour/cache-backend-file/File.php on line 663)
2. I refresh the page the site is still working
3. I put in command sudo php bin/magento setup:upgrade
4. I refresh the site and the site is down with a warning message
In video clip two I do the following
1. I put in command sudo php bin/magento setup:upgrade
2 I put in command sudo php bin/magento setup:di:compile
3. Go to the site then click on a link and the site is down again with the same warning
Warning: file_put_contents(/var/www/html/top-property-store/var/cache//mage-tags/mage---cc6_COMPILED_CONFIG): failed to open stream: Permission denied in /var/www/html/top-property-store/vendor/colinmollenhour/cache-backend-file/File.php on line 663
