I have installed Magento 2.3 on xampp. I have tried to check the CMS pages, blocks via admin panel but its not opening instead it says the error
Attention, Something went wrong
How can I fix this error?
Maybe it was permissions on the Notifications
Based on [ https://github.com/magento/magento2/issues/6602 ] you can:
You should check the
var/logs folder to see if something went wrong and also your server logs.
For me the issue was related to this one https://github.com/magento/magento2/issues/5418.
Gone into db table cataloginventory_stock_item and delete duplicates and then the issue dissapeared.
If that doesn't solve it, you can try:
1) cd into
pub/static and run
find . -depth -name .htaccess -prune -o -delete
2) cd into root folder and run
rm -rf var/cache/ var/generation/ var/page_cache/ var/view_preprocessed/
php bin/magento setup:static-content:deploy
If this doesn't solve it you could take the radical option to reinstall:
1) delete the vendor folder
rm -rf vendor/* and also the
composer.lock file in root.
