Hello. This week, on Wednesday, I've made available my new blog theme and a new photo gallery, using Gallery 2 and WPG2 plugin to manage users access to galleries (all of them private to guests and open to registered users). Everything was running smoothly up to today, when I realized that the access to single post is very slow, taking up to 20 seconds on loading and sometimes it doesn't even load. Since it is the first weekend of my blog with users registering to access galleries, I thought it could be something related to Gallery2. But the strangest thing is that everything works nice - dashboard, archives access, home, categories access - the only problem is accessing single post.
Please, can someone help me with this issue?
