Your database is being updated in the background STUCK!

I have enabled debug and noticed that there is a fatal error that says:

[04-Aug-2018 08:14:19 UTC] PHP Fatal error: Call to a member function remove_cap() on null in /home/artgrain/public_html/wp-content/plugins/woocommerce/includes/wc-update-functions.php on line 1367

I suspect this is the cause, may I know anyone knows how to solve this error?

						Learn how to update

We have tried deactivating all plugins (except woocommerce) and use the default twenty-seventeen theme and the error still persist… is anyone able to help?

Hi @websprout,

The function remove_cap() refers to a remove capabilities function of WordPress, are you running the update when logged into the site using the sites main admin account.

https://codex.www.ads-software.com/Function_Reference/remove_cap

Hi Stuart,

I have tried logging in as the main admin but still it shows me the same error…

This is really strange..

Is there anything I can do?

Hey @websprout,

Have you tried logging in and performing the action with WP_DEBUG enabled to see if any further error messages display on the screen?

https://docs.woocommerce.com/document/debug-info-internal-server-500-error/#section-2

If no messages display onscreen maybe printing any errors to file could reveal something over more time.

https://codex.www.ads-software.com/Debugging_in_WordPress#Example_wp-config.php_for_Debugging

It’s also worth testing on your site by disabling all other plugins leaving WooCommerce as the only activated plugin along with also switching to a theme like Storefront. After doings so then try running the update again.

Once you have disabled all other plugins and switched theme if you find that the behaviour was resolved you can then enable your theme and sites plugins testing after each one is enabled until the behaviour returns to try and locate the culprit.

Hi Stuart,

I have logged the error and it is the same error as before:

PHP Fatal error: Call to a member function remove_cap() on null in /home/artgrain/public_html/wp-content/plugins/woocommerce/includes/wc-update-functions.php on line 1367

I have also disabled the theme and all plugins (except woocommerce) to click the update database and still it gives me the HTTP 500 error.. So I suspect that this is not caused by the theme or other plugins…

Hi @websprout.

Thanks, and it’s worth maybe trying to update the site on another web server or localhost setups like MAMP or WAMP as it could be server related.

Hi Stuart,

I have tried on another web hosting of mine and the result is the same.. beside the above php fatal error, I discovered there are several database errors below too:

WordPress database error Table 'artgrain_enggdb.ag_mod_withdraw' doesn't exist for query SELECT COUNT(*) as count FROM ag_mod_withdraw WHERE withdraw_status ="withdrawn-pending"  made by wp_dashboard, do_meta_boxes, call_user_func, custom_school_dashwidget_content, withdraw_function

 WordPress database error Table 'artgrain_enggdb.ag_sched_makeup' doesn't exist for query SELECT COUNT(*) as count FROM ag_sched_makeup WHERE makeup_status ="makeup-pending"  made by wp_dashboard, do_meta_boxes, call_user_func, custom_school_dashwidget_content, makeup_function

 WordPress database error Table 'artgrain_enggdb.ag_sched_transfer' doesn't exist for query SELECT COUNT(*) as count FROM ag_sched_transfer WHERE transfer_status ="transfer-pending"  made by wp_dashboard, do_meta_boxes, call_user_func, custom_school_dashwidget_content, transfer_function

 WordPress database error Table 'artgrain_enggdb.ag_students' doesn't exist for query SELECT COUNT(*) as count FROM ag_students WHERE status ="1"  made by wp_dashboard, do_meta_boxes, call_user_func, custom_students_content, count_student

Do these errors tell us something?
Alternatively, is there anyway I can update the database directly in the Phpmyadmin?

Thank you so much for your continuing help, Stuart!

Hi, @websprout!

The fatal error in question ( Call to a member function remove_cap() ) seems to be coming from some custom code you’ve added to your theme’s functions.php file.

I would recommend you either look for and remove that code, then force db update using this link:

https://artgrain.com.sg/wp-admin/admin.php?page=wc-settings&do_update_woocommerce=1

OR ..

switch to a default theme like Storefront (https://www.ads-software.com/themes/storefront/), and then force the db update (same link as above)

.. and if that doesn’t work == switch to a default theme like Storefront, disable and then immediately re-enable WooCommerce plugin (should rebuild the tables), and then force the update

See if any of this helps resolve your issue/s

Cheers!

Hi Rynald0s,

Thank you for your comments! I have commented out the code and now it works!

Thank you!
