Website just stopped working

Hi all!

When I checked the website http://www.tursar.net this morning it just was not there and it looked fine yesterday.
I didn't do any changes to the site yesterday either. I just worked on newsletters.

I got this error message:
__________________________________________
An error occurred while executing this script!

If you are a Contao user, contact the administrator of your website.
Open file system/logs/error.log and search for a corresponding entry.
Open file system/config/localconfig.php and add the following line:
$GLOBALS['TL_CONFIG']['displayErrors'] = true;
Read the Contao FAQs or visit the Contao support page.
To customize this notice, create a custom template file named templates/be_error.tpl.
____________________________________________

I went to system/logs/ and tried to find error.log but it wasn't there.
I opened system/config/localconfig.php and copy-pasted the "$GLOBALS..."-line to it. At least I think I did it right....
I then tried to reload.. use IE... etc etc... nothing happens.

I can still log in to contao and all the files are there.
The index.php-file has not ben changed since the 18th this month.

I sent an email to the web hotel. They just replied that I must have changed something......
Well... maybe I was sleepwalking last night but I find it hard to believe.

Before I delete everything and try to rebuild the site again... or however you do it.... I need to check with you experts.
Is there ANYTHING I can do or do I have to start over somehow?

Hoping to get help!

Hehehe...
Just as I had posted this message a friend helped me out..... so I thougth I'd paste the solution in case some other newbie like me has problems. I don't understand more than that the database had crashed somehow and that he corrected it.... wow..... How was I supposed to know that a database had crashed?

This is what he wrote:

in public_html folder there is a file error_log, and in that file there are
lots of lines like this:

[24-Nov-2010 12:47:57] PHP Fatal error: Uncaught exception 'Exception' with
message 'Query error: Table './tursarn_db/tl_search' is marked as crashed
and should be repaired (SELECT id, checksum FROM tl_search WHERE
url='index.php/home.html' AND pid='13' LIMIT

So it says that in the database tursarn_db there is one table that is
crashed.

I went to cPanel-> Databases-> MySQL Databases,
there is a section "Modify Databases", I selected tursarn_db and clicked
"Check DB",
and it checked the database, found the crashed table and corrected it.

Glad to hear you got it fixed, Marianne!

Well, "nice" to hear that someone else experienced this...
It has happened two times in a short period of time for me on two separate customer websites. The tl_search table crashed and needed repair. I can't say that I really know what has caused it but the first time it happened I was working on a custom module. The second time it crashed when working on a newsletter, just as for Marianne.

Lets keep an eye on this and try figuring out exactly what triggers it.
