thanks, the update fix the problem..

Same here, thanks for the update.

What exactly was the bug in the username field?

Entered username field contents was put into log.txt file by file_put_contents function. I left that function there by mistake. Used it for debugging purposes. On some servers, PHP scripts, probably, have insuficcient permissions on writting to that folder, producing a warning, that broke JSON formatting of results.

both arabic and english names.

hope the aurther can solove this problem.

Installed!

Thanks,... Installed and clicked.

I did notice that it suggested a username on the reg page is good even if it is not. Only fails upon initial testing, if username includes a space in it where a pre-existing username with space in it already exists. Single word no-space usernames seem to verify properly.

v:1.1.4 installed

I never got this error so that must mean it was put into a txt file. Mind telling me where it is? I like to keep any files I don't use off my server.

It is in the root forum directory. Where fractalizer_ajaxreg* files reside.

Can you please rephrase your sentence? I doubt I understood something...
