HEY! :shock:

OK, thank you both for your responses. I will try to focus on this now.
Unfortunately, the plugins are many (some I shall be removing, as no longer required).
Screen grab of my WP [url=https://pennymachines.co.uk/temp/plugins.html]network admin plugins here[/url].

As last chance (and just to test the coming 2.8.5, which about this anyway come with the same exact unchanged code) i have try to reproduce the issue adding into wordpress MUMS an user which in phpBB the username has been changed like this
[i]martinm- _yrick0_[/i] and has been transferred via plugin's single user transfer (/wp-admin/tools.php?page=wp-w3all-users-to-wp) into wordpress, which into a default mums would be not ok because the username contains spaces and underscores: then WP, cannot create for these usernames a subsite, because the username contains chars not allowed and it is used for the blog name: but we assume that on these mums users are not allowed to create subsites then it is ok to use all allowed usernames chars, like it is for a default wp, so [b] -0-9A-Za-z _.@[/b]
then i:
removed martinm- _yrick0_ from a blog, [b]no error[/b].
removed martinm- _yrick0_ from the main site, [b]no error[/b].
removed another username test directly from the main site, without removing before from a blog: [b]no error[/b].

Could you list plugins you are using?

It would be a good idea to know the plugins list you're using so i could try to reproduce the issue.

Uncaught Error: Call to a member function get_results() on string

Uncaught Error: Call to a member function get_results() on string

[code]Uncaught Error: Call to a member function get_results() on string[/code]
mean that connection values are lost and the executed query fail.

Unfortunately i do not have an answer, the unique highly customized mums site i've see that was returning
[code]Uncaught Error: Call to a member function get_results() on string[/code] on deleting an user
was about the fact that even the get_option() WordPress default function was returning an empty value (even on init) at deletion time on WP admin.
So i resolved the case directly adding values to the connection function at this time,
[c]$w3all_config_db["dbname"] = "mywebsite_phpbb";[/c]
but would have work also as it is the code now, that retrieve the value via a direct default query when connection values are lost (get_option() return empty value) deleting an user on mums: but you say that even this do not work, that mean also that the default WP query fail some way for you. I do not have an answer to your question, i would like to reproduce so to reverse the problem but i cannot in any way i tested any mums it work fine. If you discover why into your still do not work even adding manual values, please let know! Thank you!
