Support » Plugin: MyCurator Content Curation » Duplicate key name 'pr_url'

  • Resolved Vidyut



    When I update options, I get an error that says

    WordPress database error: [Duplicate key name 'pr_url']
    ALTER TABLE wp_postsread ADD KEY pr_url (pr_url)

    If I deactivate and reactivate plugin, it alerts to 208 lines of “unexpected output”.

    It was working fine, and then suddenly it started showing these errors. I installed the plugin on another blog, and noticed it offers one topic in free version, but mine allows two – I didn’t hack it or anything – it was like that when I installed. Wondering if this is related to the errors I am getting.

    Note: I am fairly competent with copy-paste and following instructions, but not a coder myself. I may be completely wrong, just that these are the three deviations from normal that emerged suddenly.

    Both of these errors do not affect your installation of MyCurator. Whenever you save options, we check whether the MyCurator data file structures have changed. The core WordPress function we use always gives this error, which we haven’t been able to figure out. As I said though, it doesn’t affect processing as the index is already created so it just doesn’t create a new one.

    The 208 lines of unexpected output are the same error (duplicate key pr_url) that happens when the plugin is activated. Again, it doesn’t effect processing.

    You are seeing these messages now because the option WP_DEBUG was set to true, probably in your wp_config.php file (or it could be turned on by some other plugin). Normally you wouldn’t see them, as was the case until recently.

    I checked again for solutions to the duplicate key error and a new posting a month ago had the solution! We’ll get it into our next update and these messages should go away.

    Finally, the number of free topics for the Individual plan has changed. Our earliest customers were able to use 2 Topics. It is now set at one Topic. Its not related to the messages you were seeing.
