As it is quite annoying as bug I just quickly made the fix to force rights on the file, it seems to work: 1st file that I uploaded was not visible, then I applied the fix and uploaded a 2nd file which was visible.
Should be ok for everybody, I hope.
If you notice pics having that problem (older vehicles pages, i.e. before the nr 270000) just report them, I can easily fix that on the server.

Still getting lots of warnings (having to try sometimes several times before an upload )

Admin : Add a vehicle

Strange I never had it since they fixed the problem. Well I guess that the server is still a little overloaded at some moments, probably not when I use the site myself, explaining why I haven't seen it.

Do you have that only with admin pages ? Or also on normal public pages ?

I think I'll switch to the other database server that I mentioned, for the little extra cost it should be much faster and solve these problems for a long time.
I'll do that on next weekend.

Today is impossible to me
Warning: mysql_connect() [function.mysql-connect]: User imcdbpro already has more than 'max_user_connections' active connections in /homez.83/imcdb/www/config_connection.php on line 14
Error in database request - User imcdbpro already has more than 'max_user_connections' active connections

Again and again

Strange, I had no problem when I used the site earlier today.
edit: ok I just had it now

Anyway as I said above, this weekend I'll switch to another server, hoping it will solve that for good (or at least for long time).

The warning strikes again

About the connections? I did not had time last weekend. I will probably have more time this weekend so I'll solve that.

Antoine: Would it be helpful if we logged off the page when we are not working on it? I tried to do some editing last night and early this am 2:50am EST, it was so bad I gave up, nothing except the home page would load. Good Luck with this issue.........Mike

No, the connexion is open at the start of the page and closed at the end, the fact that you remain connected to the site between each page is artificial, using temporary cookies in your web browser.
