So a friend I met over a forum made me a website using wordpress and everything was running great for the first week or so. (I've had for about 2 weeks) Everything loaded quickly and i could quickly upload photos to my gallery and insert them into posts. Now when I log in and try to edit I first see all the coding in the visual tab and have to wait about 5mins for the visual sectiojn to load then when it loads i try to insert a picture at the bottom and it takes another 5-10mins for the gallery to load and another 5 for the pictures to show and then when i click insert into post it acts as if it's inserted but nothing appears there. It never used to do this and I don't know why it does this. I have NO plugins whatsowever and my website is pretty bare only some text like 2 short videos and about 15pictures are on it so I know it's not a bandwith problem or anything. Also the guyt who made the website hasn't been on in a week so he can't help me and I don't know any scripting or codes for the most part so consider me a noob when you're giving me any tips! please and thank you!
Here's the website by the way if you need it.
