Strona nagle nie działa - błąd 404

[Bartek.baran]

Dzień dobry,

moja strona internetowa na Joomli nagle przestała działać. Pojawia się komunikat:

404 - Component not found
You may not be able to visit this page because of:

an out-of-date bookmark/favourite
a search engine that has an out-of-date listing for this site
a mistyped address
you have no access to this page
The requested resource was not found.
An error has occurred while processing your request.
Please try one of the following pages:

Home Page
If difficulties persist, please contact the System Administrator of this site.

Na zapleczu pojawia się taki komunikat (i nie da się zalogować):

Co powinienem zrobić, aby strona wróciła do życia?

Sama strona z siebie nie przestaje działać. Musiałeś coś wykonać lub admin serwera coś robił. Może być też działanie osób trzecich ale to już gdybanie.
Wydaje się że masz jakiś problem z Bazą Danych. Spróbuj ją przywrócić z backupu.
Jeżeli poważnie używasz Joomla 1.5 to jak dobrze pamiętam wsparcie skończyło się 2012 roku.
