Most buttons in backend wont work after upgrade to 2.3.4

[g_svan]

I get these errors in system.log:

main.CRITICAL: Compilation from source: LESS file is empty: adminhtml/Magento/backend/en_US/extjs/resources/css/ytheme-magento.less [] []
main.ERROR: Unable to resolve the source file for 'adminhtml/Magento/backend/en_US/mage/adminhtml/globals.js' [] []
main.CRITICAL: Unable to resolve the source file for 'adminhtml/Magento/backend/en_US/mage/adminhtml/grid.js' [] []

I have made it work by editing through phpmyadmin, but that just isn't doable no more...

Please help, Thanks

PS. Frontend works just fine

Hello @g_svan 

Please run the below commands:

bin/magento setup:upgrade
bin/magento setup:static-content:deploy -f -a adminhtml
bin/magento setup:static-content:deploy -f -a frontend

I hope it helps.

Hi @g_svan 

Have you removed pub/static folder once after upgrade?

You can run the commands which @Sanjay Jethva mentioned. But I will suggest below commands in sequence after correct permission.

Try the following command once:

find . -type d -exec chmod 755 {} \; && find . -type f -exec chmod 644 {} \; && chmod u+x bin/magento

You can use sudo as well.

If still face issue, then try following command s once to re generations.

chmod -R 0777 var/ pub/ generated/
rm -rf var/cache/* var/view_preprocessed/* generated/* pub/static/*
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:flush

 
I hope it will help you!

Hi Vimal and thanks for your reply.

Tried your solution but didn't help... Buttons still don't work and same errors in system.log

Okay guys, think I fixed it I just copied the requested files from an old backup and all buttons started to work
