All of a sudden I get an error when trying to access a forum

[Garibaldi]

I've had my site, www.wiscollectorcar.com up and running for several weeks now. I also have a forum on the site here: www.wiscollectorcar.com/forum/ and it has been working fine. Now, however, when I try and go to it it gives me this error:

phpBB : Critical Error

Could not connect to the database

I haven't made any changes to the site or anything except to change the logo and title of my mail service here: http://webmail.wiscollectorcar.com
I also added a mod for my forum for resetting a username but I know that isn't the problem because the forum worked great afterwards and I'm sure it isn't the issue here.

Any ideas or help would be great!!!

Now that error is fixed but now I get this one when trying to view a topic:

Parse error: parse error, unexpected '<' in /home/.nate/wiscolle/wiscollectorcar.com/forum/includes/template.php on line 60

for instance here:
http://www.wiscollectorcar.com/forum/viewtopic.php?t=91
Here is my template.php, no changes have been made:

Any ideas?

[lordsmurf]

Looks fine here.
When you add/edit code to PHP or ASP, easy to hose it all.

Backup often. Every file, everything. All the time. Can restore it when (NOT IF!) you screw something up.

[Faustus]

Go to your SQL admin and make sure the user is still added to the database. Thats all I got.

I've had my site, www.wiscollectorcar.com up and running for several weeks now. I also have a forum on the site here: www.wiscollectorcar.com/forum/ and it has been working fine. Now, however, when I try and go to it it gives me this error:

phpBB : Critical Error

I haven't made any changes to the site or anything except to change the logo and title of my mail service here: http://webmail.wiscollectorcar.com

Weird, i'm seeing the same error on http://www.convopit.com/forum/

[Garibaldi]

Thanks for all your suggestions, sorry it took me so long to respond. I was finally able to restore it from a backup and now it works fine. Like you said PHP seems to be very touchy. The forum is working great except for one thing. I installed a MOD, Quick Reply with Quote and BBCode but instead of looking like this:

It looks like this:

I've even double checked the code but it still doesn't work correctly. Any ideas?

[Faustus]

Don't really have an answer for you on that one. I would suggest, if you haven't already, getting an account over at phpbb.com since the mod designers are over there.

[Garibaldi]

Don't really have an answer for you on that one. I would suggest, if you haven't already, getting an account over at phpbb.com since the mod designers are over there.

Yep I have an account, but that is a mod from phpbbhacks.com, something not "officially" supported by phpbb, but that works fine with it and is widely used.

[mastersmurfie]

Garibaldi, I too had problems with that particular "quick reply" MOD

Only thing I could get to work was "quick_post_es" from phpbbhacks.com

other than that, check your lang_main.php file...make sure all entries are on a new line, and separated with ;

and check your *tpl files for any "wierd stuff"..

I too am new to this phpbb thing, and am learning lots of new things...PM me if you want to trade any "secrets " or see what I've done with my forums...

[Guest]

I get the error as well.
