Bootstrap3

[alex_d]

i have wamp installed with php 5.3.5

I can not comment on 'E_ALL & E_STRICT' stuff, I'm not back-end dev.

Ree,

Yeah I'm on > 5.4, so E_ALL should include E_STRICT.
alex_d, not sure what to make of the latest screenshot. If $_POST['cmdSubmit'] is set, there's no reason for $_POST['chkDisplayOtherThemes'] to not be set (which is what the notice is indicating).
If you view the source to that page, do you see this string in there?
input type="checkbox" id="chkDisplayOtherThemes" name="chkDisplayOtherThemes"
(and just to be clear by view the source I mean the source of the page in your browser, not the source of the php script).

that latest screen shot is from GS, when I open Generated Source I can see next:
<p>
<label for="chkDisplayOtherThemes">Display 'Other Themes'?</label>
<input id="chkDisplayOtherThemes" name="chkDisplayOtherThemes" value="true" type="checkbox">
</p>

So this is happening only inside GS when I select some other Bootstap3 theme and save after it
