Plugin Upload Issues

Over the last three days I have been attempting to install a new plugin. I have been having issues with the wordpress page freezing and the upload stopping, or if it does get to 100%, which is rare I get an error, are you sure you want to do this. I have attempting many things to ix this, my internet connection isn’t very fast, but I doubt this could be an issue as it never has been before. I have disabled all my plugins, and my theme and activated the wordpress 2017 one, and this didn’t help the issue, I can still upload media without any issues. I have tried uploading various plugins with the same issue, however if I install a free plugin through wordpress, it works fine, I am thinking an upload issue. I have uploaded my plugin using ftp, in a zip file and extracted using cPanel file manager, however when in wordpress the plugin won’t display under the plugins area to activate it. I have searched for everything on google that may help and still have had little success with this problem.

I have checked my host has available storage space left. I have administrative rolls, I haven’t altered any other backend files as I don’t believe anything should have been altered since I last uploaded a plugin.

I have emailed my hosting provider for the error logs my hosting provider has asked me to check cPanel/errors, which displays no errors and public_html/error_log, which is a file that I don’t have and can’t find. Is this a file I should definitely have? Anywhere else I can look for error logs? I have tried re-installing the newest version of WordPress on itself, this didn’t fix the issue.

I am desperate to fix this issue and am happy to provide login credentials to anyone that may be able to help me further with this.

Can anyone please help, it would be greatly appreciated,
Thanks,
David…
