 Hi, I was getting a lots of errors while doing disable the cache from opencart admin by clicking on this button. like this "Notice: Trying to access array offset on value of type null in vendor\scss.inc.php on line 1753" to fix this error. I did change this code in the following files storage->vendor->scss.inc.php $key = $key[1]; to $key = isset($key[1]) ? $key[1] : null; Now everything is fine and working great 😅
