[desideria]

I don't know why, but from some days ago I started to receive errors: when I add some book, when I create a column, when I create a library, when I move the books from a library to another....

Here are just some of this errors, hope somebady can help me with this:

I had the version 0.7.53 when the errors started to appear and I still have them although uploaded it to 0.7.54 version.

Thanks in advice.
