Unexpectedly, I faced an issue that does not allow me to move forward: while uploading photos to the website I got a "HTTP Error". Meaning, I just cannot upload images to the website, at all. I try to upload (via Wordpress uploader as well as via browser only (also, I switched several browsers to try all the options) but in response I just get the "HTTP Error" thing.
I've tried to resize the set standards for images on the website, tried to take a look at the code (and even change it following recommendations from various forums) but nothing helped. I still cannot upload a single image on the website, the "HTTP error" comes up and that's it.
