If user solves CAPTCHA incorrectly it displays 'you must enter name e-mail .... ' etc. I would like it to display 'Error in CAPTCHA' then!

Hi,

right, that hint is missing...

Hi,

this is fixed in CVS.

I had two issues:

1)If you delete a PROPOSED entry, it is still displayed as existent. Next you try to delete it displays 'entry was deleted'. I think the list of entries to 'approve' should update when something is deleted from here.

2)Display 'Error in Captcha' when it is so.

Both are fixed?

Hi jazcyk,
this one is fixed.

Hi jazcyk,
could you try the next nightly built snapshot? I'm not able to reproduce this issue.
TIA

[jazcyk]

I reproduced with 1.6 snapshot that I DL'ed 5 minutes ago.
Problem persists (testd with Firefox and Opera)

To reproduce:
1) as a USER 'add content' .. 1 item
2) as ADMIN .. approve records .. delele it .. confirm!
3) without restarting browser or refresh once more 'approve records'. The deleted item is still displayed. Delete it again .. confirm and 'has been deleted' is displayed.

Probably browsers use their cache data and don't refresh that page. Can you force them to do from your code?

But it is a very small cosmetical thing!
The captcha-fix is confirmed!

[Thorsten]

Hi,

this seems to be a cache problem. We send headers to force browsers not to use the cache in the backend. I'll try to make this better.

now I met the first captcha that I could not resolve:


What is the 6th character? 'a','S' and '6' don't work!

[Thorsten]

Hi,

maybe a 'B'?

bye
Thorsten

[jazcyk]

on an 'X' maybe?

Well it is gone now, I have no option to try. But maybe the distortions in the captcha class is just a little too much and the statistic variations should be 'turned down' a little?

[Thorsten]

Hi,

I will test it when the new version is finally released. If there are too many negative postings we can reduce the distortion...

bye
Thorsten

[jazcyk]

It is no big issue either.
You can always refresh and get a new!

I now did a systematic test.

Of 50 captchas generated by phpmyfaq beta 1.6 only 30 were unambiguish, I found 11 somewhat unclear, 6 were difficult and 3 were impossible to solve.

Common problems:

* Lowercase 'l' and uppercase 'I' often looks similar
* With some characters it is impossible to distinguish between lowercase and uppercase, like 'v' and 'V', 'o' and 'O' (and '0' (zero)) etc. but the system only accepts one of them
* '7' and '1' can sometimes be difficult to distinguish
* uppercase 'B' often looks like lowercase 'a' (this was the one we had before)
* uppercase 'M' is often displayed more like lowercase 'm', but 'm' is not accepted.
* sometimes the background is very disturbing. I think a lot of old people and other people with a bad sight will have serious problems with this.

The three impossible ones are mailed to Thorsten.

Hi jazcyk,
just a note for all PMF users: the validation performed against tha captcha code is case insensitive and FYI the set of characters used for generating the captcha code is an upper case one.

The three impossible ones are mailed to Thorsten.

Thanks for your testing !
We've some keys for the tuning such as the distortion algorithm and, first of all, the set of the characters used for creating the captcha code.
We'll look at the best trade-off.
