Yep.. I suppose this started to happened when I tried to export the contents (style, widgets, customized contents, theme, etc.) from English version to the other. This process stuck and I had to interrupt it and to do all the process manually, but I’m not sure if this attempt made some changes during the exportation. Besides, I tried dozens of other ways to try to solve this problem (dowloaded many plugins, for instance) and got a big headache on this.. Anyway… I prefer keeping the website with these failures than trying to start from the very beginning again. 🙁
Yep, actually I added the facebook comments system after the problem has appeared, so… no relation. Anyway, thank you for trying to help me and sorry for disturbing you so late in your country. 🙂
Ok, I’ve just add a widget on blog right sidebar. You will see the menu “documentos” just below the main content.
