From about two days, I can't use some options on the site, f.e. I have a problem with editing and removing my posts, and with entering on my profile. Sites aren't loading or opening very slowly.
I didn't install any new software etc.

?!!!

For the fact that it is slow is must come from your ISP or your PC.
What kind of problems do you have with edit/delete/profile?
Do you use the option to auto-login (i.e. remember the user & password) ?

Yes, I use auto-login.
Edit/delete/profile - these options often don't work and I have only a white window in explorer.
Everything else is working correctly.

I do not know what it could be if you have the autologin enabled, as it previously solved similar problems.
Did you try in another webbrowser?

No. Alright, thanks, I will check settings in my PC.

Funny, I can open my profile every time when I switch to French or German version, but still I can't edit posts.

By "open" you mean edit?

Yes, also edit.
But as you said I've tried with another web browser - with Opera and now everything is ok.

Depuis ce matin, le site est anormalement lent!!! Il faut 3 plombes pour charger une image ou pour passer d'une page à une autre... Pb de serveur?

J'ai pas eu de problème Ça doit venir de quelque part entre le site et toi, ou alors ça marchait justement quand je suis allé dessus.

This page appears when I click on the link to my comments page-

This seems to be the same as garco had recently: http://forum.imcdb.org/forum_topic-1711-IMCDB_down.html
Do you still have the problem ?

Im not having any problems logging on.
