Ajax error when searching on members page

[tomarppe]

I have updated to version 4.2.6 and this ajax error is back:
DataTables warning: table id=tbl_members - Ajax error. For more information about this error, please see http://datatables.net/tn/7

Webserver Error log:
Wed May 03 15:28:26.554245 2023] [php:error] [pid 6295] [client 193.210.229.159:25292] PHP Fatal error: Uncaught Error: Call to a member function fetch() on bool in /var/www/cumulusrf/members/adm_program/modules/members/members_data.php:214\nStack trace:\n#0 {main}\n thrown in /var/www/cumulusrf/members/adm_program/modules/members/members_data.php on line 214, referer: https://cumulusry.fi/members/adm_progra ... embers.php

Hi Tom,

could you try to locate the problem and search with different characters. Maybe it will work with some members. After that we must try to identify which members have the problem and which special data they have.

Best regards

The error is regardless of with what character I search, the strange thing is that in groups and roles the search works fine.
I have installed Admidio for another club and there is no problems there. Both are on the same server and both are now on version 4.2.14

The error log shows the following:
[Tue Dec 19 18:15:02.000066 2023] [php:error] [pid 17597] [client xxx.xxx.xxx.x:52174] PHP Fatal error: Uncaught Error: Call to a member function fetch() on bool in /var/www/xxxxx/members/adm_program/modules/members/members_data.php:221\nStack trace:\n#0 {main}\n thrown in /var/www/xxxxx/members/adm_program/modules/members/members_data.php on line 221, referer: https://xxxxxx.xxx/members/adm_program/ ... embers.php

Any idea on where to search for the problem?
