is Magento 1 still being supported at this moment? Because I see no replies in the issues that are posted recently like 2019. All the answers are two years most of them are no longer relevent like this
Warning: is_readable() expects parameter 1 to be a valid path, string given in ...../web/lib/Varien/Io/File.php on line 535
I have been sitting with this error and doesn't seem like I am getting any answer in most magento platforms even here I haven't been answered.
