warning: Missing argument 1 for og_feed() in /home/ecentres/public_html/modules/og/og.module on line 2033.

In the principle, I passed some data of users and nodes to the website. Now I have problems with the forum and taxonomy and groups, seems that not all is coordinate, raising some warnings from some modules.

I think that this cam vbe from the initial sequences values that I dont have all fixed, What do you think?
I think that there aren't any incompatibility between the aggregation module and groups?
what can be a good solution? the table of variables is now too much complex to be modify.
