Help my website has a fatal error

Using an FTP Client such as FileZilla or your web host provided file management tool, please rename the errant plugin’s folder:
/wp-content/plugins/aryo-activity-log
to:
/wp-content/plugins/old-aryo-activity-log

Then, make sure to clear any server cache in use and your local browser cache.

Please run site then and report back.

Seems to be an issue with that plugin and that is how to deactivate it when you cannot log in due to an errant plugin.

If you FTP into your site, go into the wp-content/plugins directory and rename ‘aryo-activity-log’ folder to something else, does that get you into your admin page?

I tried to install a new version of wordpress ( had 3.6) version 3.8.1, but now my webshop is a total chaos, due to 17 found errors, I have paste 4 examples here:

Failed to load resource: the server responded with a status of 404 (Not Found) https://localhost:8888/wp-content/themes/opulence/includes/js/scripts.js?ver=3.8.1

Failed to load resource: the server responded with a status of 404 (Not Found) https://localhost:8888/wp-content/themes/opulence/functions/css/shortcodes.css

Failed to load resource: the server responded with a status of 404 (Not Found) https://localhost:8888/wp-content/uploads/opulence-custom/custom.css

Failed to load resource: the server responded with a status of 404 (Not Found) https://localhost:8888/wp-content/uploads/2014/03/Logo-lizzy.png

most of the errors are about, not finding wp-content, wp-includes.
Please help me out, I have put a lot of hours working in my webshop and don’t want to start over.. I think there has gone something wrong in the structure of my maps.

Thanks in advance

u know the link you have posted are of localhost and not actual server + u should open a new post for your issue
