Error while upgrading OJS 2.4.8 to OJS 3.1.0

Hello everybody,

I am trying upgrade my OJS 2.3.7 to OJS 3.1.0. Firstly, I made an upgrade from OJS 2.3.7 to OJS 2.4.8, and all succeed without problem. Finally I tried to upgrade from OJS 2.4.8 to OJS 3.1.0 and I got the following error.

Both upgrading process were made using web upgrade function.

ojs2: DB Error: ERROR: relation “articles” does not exist\nLINE 1: …ELECT article_id, journal_id, review_file_id FROM articles W…\n ^, referer: http://localhost/ojspujcali/index.php/index/install/upgrade

I don’t know how i can resolve this problem, may you help me?
