I have just upgraded from Magento
Redis was previously working fine, however, when I activate it now through my env.php file, I am receiving this error.
Warning: substr() expects parameter 1 to be string, object given in /http/vendor/colinmollenhour/cache-backend-redis/Cm/Cache/Backend/Redis.php on line 1188","1":"1 substr() called at [vendor/colinmollenhour/cache-backend-redis/Cm/Cache/Backend/Redis.php:1188]
What could be causing this?
When i comment out the Redis configuration in the env.php file, the site works okay but it will not show any updates.
I have tried
rm -rf var/generation var/di and all other normally necessary commands but none of them seem to work.
