You simply need to follow the steps on the Debug ID page. Someone might be able to translate those into Spanish for you, but we can't help you without a Debug ID that shows your sync attempt.
it appears a message " database with errors" , the message suggest to repair the databes with a link but the problem is that my lybrary is bigger than 100 Mb
I don't know how to check the size . When I check the storage in the web library is 0, I don't know why.
I have the database in an external device and when I check the size of the zotero folder ( in the windows programe pressing the right key of the mouse over the ZOTERO folder and looking at the properties ) is 11.9 GB
I have tryed to upload the database and it tells me that is bigger than 100Mb
I mean, if I have upload the zotero.sqlite, there is any message, I supose the upload was correct. Isn't it?
Sorry about that, but if it is well upload, where I can find the next instructions to restore that file. In these instructions "Zotero Database Repair Tool" don't explain anythink else.
You should then check your database integrity from the Advanced → Files and Folders pane of the Zotero preferences.
