This can happen when your browser has too much cookies for the site (which could be caused by the ad scripts).
If you try to clean the cookies just for imcdb (not all cookies) it should solve the issue.
You can also try to use the other version of the domain, with or without www, so either https://www.imcdb.org or https://imcdb.org depending on which one you are using when you have the issue.
I should try to increase the max header size.
When you can reach the site, you can try checking this page to see the total size of cookies: https://www.imcdb.org/cookies.html or https://imcdb.org/cookies.html
In my case it gives a little less than 4200 bytes, I think the limit is at 8192 bytes.
(I tried to include there a function to delete the existing cookies, but not all can be deleted via javascript, so the most effective is doing it yourself in the browser, but in non-Firefox browsers I'm not sure if you can easily delete the cookies for one site only)
