errors with a plugin – Google Captcha (reCAPTCHA) by BestWebSoft

i first had these issues here:
https://www.ads-software.com/support/topic/are-you-sure-you-want-to-do-this-35/

so i decided that i will just upload the backup version that i think was working normally (i made it before moving to another server).

but now i am having some other issues for some reason… :
1) Opera and Chrome will not even log in to the admin page (just reloads the page) and Firefox just logs in without showing any google puzzles… (just ticks the robot box)
2) on the admin page, the “Google Captcha (reCAPTCHA) by BestWebSoft” plugin keeps telling me:
“To use Google Captcha you must get the keys from here and enter them on the plugin setting page.”
and after i enter both of the keys it says:
“WARNING: The captcha will not be displayed until you fill key fields.” (+”Enter secret key” in red color)
3) when i try to upload a small picture into the media files (or straight into the post), it gives me “HTTP error” now… (while the upload worked perfectly fine with the previous and continuous site that i had…)

and again… all plugin and theme updates work perfectly fine…

both of the versions gave me this error tho:
“count(): Parameter must be an array or an object that implements Countable in /home/xx/public_html/xxx/wp-includes/kses.php on line 893”

and i do have like a foreign letter (?) in my domain name, so maybe that also affects something?
