Hi. Suddenly yesterday I installed a module and then frontend works fine but backend doesn't work, every url gets a blank screen. I uninstalled the module via terminal and then it works fine again. But now I tried to install another module and the same problem, so it's not a problem of this module. Even I tried installing a module with no actions inside and doesn't work.
I found a non-installed module with blank space in its folder name, but it's a module which never has been installed. I fix its name, just in case, but the problem still remains.
Log doesn't show any error, even with log debug mode activated.
What can I do? Thanks.
