They're opening fine for me using google chrome & firefox.

Also you have over 400 requests on every page. You might want to trim that down as each request adds to the load time.

Comparing it to my site, mine only makes 28 requests on every page load and if a user is returning then it's only 18 requests for them. Refer to what I said earlier about cutting back on third party scripts or they will continue to put a burden on your site.

Also it looks like you have alot of active members who may be posting images from third party hosts. This addon can help to localize them & reduce page load time for returning visitors.

It looks like if you hosted the images on your domain instead of photobucket you could shave off 71KB... quite a bit.
Also if you scale the images you can save over 480KB... all in all around half a megabyte.
This article can help you with image scaling since you use vbseo https://vborg.vbsupport.ru/showthread.php?t=276910

And finally if you defer the parsing of javascript... as I mentioned in another post, you can save another 190KB or so worth of bandwidth.

In order to load a page, the browser must parse the contents of all <script> tags, which adds additional time to the page load. By minimizing the amount of JavaScript needed to render the page, and deferring parsing of unneeded JavaScript until it needs to be executed, you can reduce the initial load time of your page.
