"404 Oops! That page can’t be found." when doing various admin things

[rustneversleeps44]

My store uses Wordpress for its website, GoDaddy as provider (yes I know, lol) and WooCommerce plugin for adding products. Very often, when trying to do anything admin related, whether it be adding products or simply trying to update a plugin, I get hit with the "404 Oops! That page can't be found." page. I've tried the hyperlink fix that many suggest and I tried editing the htaccess file. What else is there to do? I have a lot of products I need to add and it takes me all shift just to add 4 or 5 because of the constant 404'ing. Luckily, the customer front-facing part of the site doesn't suffer from this issue so at least it isn't affecting our shoppers but it's otherwise aggravating to constantly deal with.
