They still work not ...
maybe because my b2evo is 1.9.3. ? and plugins are for 1.9.0. ?

I'm no expert, but there seems to be something different in how php5 handles memory limit. Search these forums (and google) for a better answer, or try limiting it downward instead of upward.

turingtest should be a small plugin, relatively speaking, but you might want to look at your total plugin load. Way back in the days of 1.8.1 a good idea was to delete from your server plugins that you don't use. It certainly can't hurt in later versions, but I don't know if it will help.

Oh and plugins generally are considered for 1.9.*, though it's possible a plugin here or there will work in *.*.1 but not *.*.2 and so forth. I know turingtest works in 1.9.3 because I use it in all my installations.

Thank you EdB for suggestion !!!!!
I can't believe, but after I delete some unused plugins - the plugins screen was OK.

turingtest now work - no problems. Thank you for this plugin :-)
about captcha here is problem - but i will ask about it in bugs forum ...

When you add too many plugins and your memory limit is too low, PHP will just die before having a chance to output anything ... :/

2 solutions:
- either delete some plugins
or
- increase your memory limit in php.ini
