I'm spending 2 days on google to solve this problem(s), and tried many solutions without any success. Please help. :)
I'm new to Magento and using version 18.104.22.168 on WAMP 3.0.6(64bits).
Tried many extensions to install via Magento Connect but without any success. It keeps give me a message: "Exception during cache and session cleaning".
Also tryed to manualy download and copy/paste content in root folder, and then logout/login to admin panel to see changes and they are installed, but doesn't work becuse cache isn't cleaned i suppose. Here is the example of Advanced Code Editor extension.
$this->_fileHandler = @gzopen($this->_filePath, $mode);
$this->_fileHandler = @gzopen64($this->_filePath, $mode);
but then is even worse, because after try to install it extension it gave me an error on front end and backend page, and can't access it at all.
