Hi, i'll try to describe the first problem in steps.
I am using the default joomla login module and the redirection page for logging in is the home page with url: http://www.clickartist.it but when a user logs in, for two days now, the url becomes: http://www.clickartist.it/index.php/latest even though i have no menu called "latest" (i have installed the demo package initially and now it's all disabled and can find no latest menu there even). Now, even though the redirection url for home page has changed, strangely the page loads fine. The problem occurs on the log-out session though.
The logout is set to redirect to the home page again, but it gives the error of the screenshot attached. By refreshing that page it loads fine afterwords.
My second problem occurs when trying to install the latest version of the template. When trying to install the gk_fashion_J!25.zip i get the following error: -1- An error has occurred. Copy failed. When trying to install the gk_fashion_rest_files_J!25.zip the error is: There was an error uploading this file to the server. I tried to install other extensions and they install just fine.
Any ideas to solve that issues would be much appreciated.
