Title: Database field configuration Last modified: March 20, 2018 --- # Database field configuration * [hansbl](https://wordpress.org/support/users/hansbl/) * (@hansbl) * [8 years, 2 months ago](https://wordpress.org/support/topic/database-field-configuration/) * Hello, * I am having the following issue: * In the admin dashboard I have no Database field configuration window anymore. If I open the link in a new window I get the message: * Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later. * I have already deleted the plugin and installed it again, but no result. * Do you have a solution? * Thanks in advance for your help. * Regards, Hans Viewing 15 replies - 1 through 15 (of 16 total) 1 [2](https://wordpress.org/support/topic/database-field-configuration/page/2/?output_format=md) [→](https://wordpress.org/support/topic/database-field-configuration/page/2/?output_format=md) * Plugin Author [Roland Barker](https://wordpress.org/support/users/xnau/) * (@xnau) * [8 years, 2 months ago](https://wordpress.org/support/topic/database-field-configuration/#post-10096306) * Is this the only page that is giving you problems? When did the trouble start? Did you install any plugins recently? What php version are you using? * Thread Starter [hansbl](https://wordpress.org/support/users/hansbl/) * (@hansbl) * [8 years, 2 months ago](https://wordpress.org/support/topic/database-field-configuration/#post-10097918) * Thanks for your quick answer. I am using PHP 7.0. Recently I have installed 2 plugins: * Insert PHP Code Snippet and Really Simple SSL * Deactivating both did not help. Other than that I also moved the website to another ISP using “Duplicator-Wordpress Migration Plugin”. I think after this and installing “Really Simple SSL” the trouble began. * I have also deleted and installed again “Participants Database”, but that didn’t help either. * Regards, Hans * Thread Starter [hansbl](https://wordpress.org/support/users/hansbl/) * (@hansbl) * [8 years, 2 months ago](https://wordpress.org/support/topic/database-field-configuration/#post-10097919) * Yes, this is the only page that is giving problems. * Regards, Hans * Plugin Author [Roland Barker](https://wordpress.org/support/users/xnau/) * (@xnau) * [8 years, 2 months ago](https://wordpress.org/support/topic/database-field-configuration/#post-10100525) * OK, well,the best way to proceed here is to set up your php error log and see what comes up when you attempt to load that page. * Since it looks like a server issue, you may want to ask your web host if they see anything in the server logs that might help see what the issue is. * Thread Starter [hansbl](https://wordpress.org/support/users/hansbl/) * (@hansbl) * [8 years, 2 months ago](https://wordpress.org/support/topic/database-field-configuration/#post-10102411) * This is what’s report in the log: * [22-Mar-2018 08:57:16 Europe/Amsterdam] PDb_List_Admin::initialize list query = SELECT * FROM ldizl_participants_database p ORDER BY p.date_updated desc * [22-Mar-2018 08:57:23 Europe/Amsterdam] PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 1065105008 bytes) in /home/blaaugh278/ domains/loozermarsnoord.nl/public_html/wp-includes/wp-db.php on line 3184 * Increasing the php-memory-limit didn’t help.

But I really don’t knoe if this is the right solution. * Thanks for your reaction. * Regards, Hans * Plugin Author [Roland Barker](https://wordpress.org/support/users/xnau/) * (@xnau) * [8 years, 2 months ago](https://wordpress.org/support/topic/database-field-configuration/#post-10113257) * Thanks, but that is kindof bad news for me as I don’t know why. The plugin should be compatible with any php version greater than 5.3, so I want to make sure this won’t happen for other users. What php version were you running before? * [Mike Meinz](https://wordpress.org/support/users/mikemeinz/) * (@mikemeinz) * [8 years, 2 months ago](https://wordpress.org/support/topic/database-field-configuration/#post-10113308) * [@hansb](https://wordpress.org/support/users/hansb/) 1.
