(Drupal 6.28) Blocks list suddenly doesn't show correctly I realized today that blocks list (admin/build/block page) doesn't correctly show  all the blocks implemented in the site.
Most of the blocks are set as disabled and others are set in the wrong region, while fortunately the site displays every block still perfectly.
I have a custom theme (Zen subtheme).
The only "strange" thing I did recently was the installation of a new module which involved the assignment of a new block to a region.
Is there any way to restore the correct blocks list?
Maybe if I don't make any change to blocks system (and save the new configuration), my site will always display correctly, but I would prefer to have the correct blocks list restored.
Yes, I could draw a manual scheme of all blocks in the site (pages, views, etc.) and use it in case of disasters, but if I could restore it with a module it would surely be better
Thanks
That to me looks like an issue with theme update. Did you changed your theme recently. It yes, then try clearing your cache.
