So after I press "Install" on a plugin that I want to install to my page I get "Internal Server Error" and message, that the plugin already exists. (Even I am installing a plugin for the first time, there is no folder in wp_content and plugin.) Even, that there was an error message, the plugin is installed and all I have to do in "Activate" it in plugins tab.
So, I can install any plugin anyway but is it annoying, that I have error message every time. Can I fix that somehow?
Thank you for your answer.
