Forum:Database error

I have just created my new wikia (http://fr.maths.wikia.com) and when I edit articles, I have an database error

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

SELECT ll_lang,ll_title FROM `langlinks` WHERE ll_from = '22' FOR UPDATE

from within function "LinksUpdate::getExistingInterlangs". MySQL returned error "1146: Table 'frmath.langlinks' doesn't exist (paris.wikia.com)".

Well, the article is well posted but that obstructs with the update of the bonds (sometimes they don't update). The error is :

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

SELECT COUNT(*) FROM `filearchive` WHERE fa_name = 'Mathswikia.jpg' LIMIT 1

from within function "Title::isDeleted". MySQL returned error "1146: Table 'frmath.filearchive' doesn't exist (paris.wikia.com)".

With the same kind of errors, I can't post images whereas for a site of mathematics, the images are capital (especially in geometry).

Please Wikia, can you repair me rather quickly this problem ? Thank you Clembou
