Thanks @Damian Culotta, checking the logs i found that there is a php method on failure. I am currently working on it.
I found the next error in the log:
[2018-05-31 22:46:30] main.DEBUG: cache_invalidate: {"method":"GET","url":"http:/","invalidateInfo":{"tags":[],"mode":"all"},"is_exception":false} []
Please let me know if you have any clues.
Thanks
@Damian Culotta to add, the problem started just befor saving the configuration of the payment module in: Stores>Configuration>Sales>Payment.
Thanks again
Hi @vholkano
I have seen the New error which you have posted and looks like its not an error , cache is invalidated.
Now run below commands in sequencially
rm -rf generated php bin/magento setup:di:compile php bin/magento setup:static-content:deploy -f php bin/magento cache:clean php bin/magento cache:flush
That might work for you !
