I'm trying to uninstall the "Browsing History Recommender" but I get the HTTP 500 Server error. I want to remove this module completely from the database and FTP.

I have been searching for a solution but no luck, I have also read this question. How to manually uninstall/purge modules?

Please Help. Thanks

  • HTTP 500 leaves full error message in server's error.log - could you try and provide it to us? – Mołot Jul 8 '13 at 15:25
  • @Mołot is error.log part of Drupal files? Would I have it on my FTP account? – Siya Stoan Sosibo Jul 8 '13 at 15:51
  • Nope, unless your host made it available to you. Many do. If so, you will have public_html or similar directory for your web files, and next to it dir named like logs. If not, you will probably need to ask your provider - unless answer below is sufficient. – Mołot Jul 8 '13 at 17:09

If you have access to ssh, use drush to disable and uninstall the module. If you do not have access, disable your module, set the status to 0 for the module name that you want to disable.

UPDATE system SET status='0' WHERE name='module_name';

And then you can manually delete the table "history_rec_user_map".

It however has two variables ('history_rec_uid_watermark' and 'history_rec_last_aid') in the variables table. Use variable_del to delete them

To remove modules, you have to remove them from your server's modules directory (usually sites/all/modules/).


To delete the modules blocks use delete from block where module = 'MODULE'

  • Thank You, it worked. but I'm still having the following error if i'm in the edit user profile page. I'm not sure if I should ask as a new question. see the following comment. – Siya Stoan Sosibo Jul 8 '13 at 20:15

  • Thank You so much. I ended up deleting all the blocks manually from the Blocks table. Thank you again. :-) – Siya Stoan Sosibo Jul 8 '13 at 20:52
