How to change the number of characters in meta description item card. In the Russian language is impossible to enter more than 130 characters descriptions in English 250 characters. I would like to change the number of characters, for example up to 400 regardless of the language used. In the keywords field, you can enter the required number of characters without problems.

It's not a bad character that prevents entering the whole description?
Example a double quote can do some problem

There are no incorrect characters. I would like to know in which file you can change the number of characters that are responsible for the output in the product card meta tag discription and keywords . In the meta admin panel, the text is fully saved and edited. In mysql, the value for these fields varchar 400 .

You should not modify it, on update virtuemart, the table and structure is checked and the size is reset to the old value.
If Milbo read the message, it can include longer size for next release.
