Captcha using TTF & GD

I just moved to a different host. Now, I'm having a small font problem on my main site.

http://www.ktnaturals.com/index.php?main_page=contact_us

What's strange is that I have a test store in just a directory under the root. That one's displaying fine.
http://www.ktnaturals.com/testshop/index.php?main_page=contact_us

The 2 hosts run different versions of PHP, Apache, and MySQL. But that doesn't explain why my testshop displays it correctly... I wouldn't worry so much, but I know some people are going to complain that they can't read it...

I compared the captcha files for both, and I checked the settings, and they're identical.

The only difference is the database... I normally apply the same updates for both stores, so I don't even know where to check...

I tried all 3 image formats, as well as adjusting the font size. Nothing works. I seemed to recall an update that I applied to this mod a while back that fixed this issue at my old host. Maybe I need to undo it? Can someone point me in the right direction? Thanks!

Figured it out... Somehow, the fonts file was missing with the font file. I re-uploaded it, and all is well.

I am having the same problem -- any help on this error? ZC v1.3.7, MySQL client version: 4.1.21

WittyMom:

Did you copy & paste or use the upload option when you tried to apply the sql patch? Copy & paste is the best way to do this.

No, copy & paste won't work with this one because it calls in fields that it creates in other tables.

I had modify the script myself. The problem(s) were:

1. Field names weren't encased in these
2. Field values weren't encased in 'these' -- namely 'NULL' and the values for "Order"

The first part of the script ran fine where it added a field to the configuration_group, so I went and got the ID for the new field and in subsequent code I replaced:

@configuration_group_id

with..

'ID#' (the actual #)

...I also had to add the prefix to "configuration"

I have no idea why only a couple of us had this problem! I got it from the same download screen everyone else did. I don't know much about SQL versions, but maybe that had something to do with it.

Shalom all,

I installed ths mod and it worked great on every page it's supposed to except for the contact_us page which it simply loaded a blank page on. When I uninstalled it the page was there again... Has anyone else had this problem and, if so, how did you fix it?

Shalom.

Copy/Paste & Execute work fine with this and other sql-scripts.
Upload & Execute don't work with magic quotes in 1.3.7.

Just a FYI.

Running cpatcha mod on ZC 1.3.7.1

Just updated host to Apache 2.2.6 and PHP 5.2.5 (and Apache and PHP now run as CGI and suphp and suhosin installed).

The captcha on contact form still works fine ;-)

Thanks Andrew.

P.S. So how well are the techniques used by this mod holding up?

Recent reports suggest Yahoo's captcha has possibly been cracked for a 35% success rate. (success defined from perspective of the spammer... 35% is considered very good accuracy)

Does anyone has CAPTCHA updated for 1.3.8a?

stevefriedman71:

Does anyone has CAPTCHA updated for 1.3.8a?

Sure. If you will simply follow the instructions to change the files, everything will be fine in 1.3.8.

what instructions??? i still have the issue i posted in post #246...
it worked just fine in 1.3.7 and now it doesn't

i have updated this to support ZC1.3.8a and Links Manager 3.3.1, and am sending it to the OA

Dear Andrew,
I'm facing a problem in shop after installing the Captcha Mod,
the images are not visible, i'm running the latest zen cart and latest captcha mod,
i'm hosted with bluehost running php5, my test rather live site is http://eshoppe.flahzasystems.com
Could you help me to over come this issue

I installed this and it works great with one SMALL issue.. The input is supposed to be case sensitive, but in my testing it's not.. Is there something I need to tweak to adjust this? Doesn't matter if I enter upper of lowercase letters.. As long as I enter the RIGHT letters and numbers, it will accept the input as valid regardless of whether I entered them with the right case..

If you look closely, it says "case insensitive." I changed it to say "not case sensitive."

KTNaturals:

If you look closely, it says "case insensitive." I changed it to say "not case sensitive."I appreciate your response.. Yes I realized how the text reads.. (which is what prompted my inquiry) If there is no other solution, then I certainly will edit the form and remove the text altogether. (since it's not case sensitive, IMO it doesn't need to be there

However, it would be nice if this WAS case sensitive.. It helps increase the security of my forms..

Are you confident that you really need? The more complex form of the less chance that it will use the normal visitors.

I can add an option in configuration.

I can't see your site - http://eshoppe.flahzasystems.com. "Site not found".

a_berezin:

Completely agree.

IMHO I don't see any need for case sensitive option. I have found the module works just fine and keeps bots from submitting my forms without case sensitivity.

Providing a case option is just one layer of confusion that my customers and shop owners whom I support don't need.

The string stating the code is NOT case sensitive is just fine and can be easily manipulated via a text editor if needed. I have yet to hear from a customer whom did not comprehend the instructions.

Invest your time in more meaningful efforts ;-)

I can add an option in configuration.Honestly, if it were up to me, I would just change the bloody text on the alert and call it a day.. However the client inquired about this.. and I just wanted to have a complete answer when I speak to him.. I will try to "talk him down".. He's VERY difficult.. sigh Phrases like "Ease of Use", "Best Practices" and "User Experience" don't seem to mean much to him, so instead of "making up" an answer, I just wanted to get an answer on this from here before I go back to him with a response/solution. It was HARD enough to talk him into using this mod.. (he thinks the security image is "ugly" sigh) Now he's asking about this. sigh

You don't need to make any changes:smile:. I just wanted to know if there was something I missed in the configuration. Apparently the answer is that the text on the forms is a typo.:smile: No worries..

Woodymon:

Completely agree.

Providing a case option is just one layer of confusion that my customers and shop owners whom I support don't need. Not debating the merits of this.. However, I asked the question because my client asked ME the question. I wanted to get an answer before I gave him a response.. It's HIS website.. If he INSISTS on this feature I wanted to know if there was even an option for it..

Woodymon:

The string stating the code is NOT case sensitive is just fine and can be easily manipulated via a text editor if needed. I have yet to hear from a customer whom did not comprehend the instructions.I realize that.. Again I was asking because my client asked me.. I could have "made up" an answer for him or told him an answer based on what I thought he should do, but I don't work like that. So I chose to at least make the effort to get an answer to his question.

Woodymon:

WoodyI consider customer satisfaction a meaningful effort. :blush: But thanks for your response.
