And will my users be able to sign up without using it? Meaning will disabling captcha do any harm to my users' signing up process?

$captchaField = new CaptchaField('captchaField');
        $this->addElement($captchaField);
        $controller->assign('display_photo', $displayPhoto);        $controller->assign('display_terms_of_use', $displayTermsOfUse);
        if ( OW::getRequest()->isPost() )        {            $captchaField->setValue(null);
            if ( isset($userPhoto) && isset($_FILES[$userPhoto->getName()]['name']) )            {                $_POST[$userPhoto->getName()] = $_FILES[$userPhoto->getName()]['name'];            }        }

Can you please define in details how can we actually do this?

I tried but when I did it, I got a blank login page.

Note: make a copy of the join.php file before you start editing and save the copy, for example on your desktop. In case of any issues use saved copy to reverse incorrect changes.

Go to ow_systemplugin/base/controllers →find join.php file → open this file in an editor you are comfortable with → find following piece of code:

 $this->setEnctype('multipart/form-data');

$captchaField = new CaptchaField('captchaField');

$this->addElement($captchaField);

$controller->assign('display_photo', $displayPhoto);

$controller->assign('display_terms_of_use', $displayTermsOfUse);

if ( OW::getRequest()->isPost() )

{

$captchaField->setValue(null);

if ( isset($userPhoto) && isset($_FILES[$userPhoto->getName()]['name']) )

{

$_POST[$userPhoto->getName()] = $_FILES[$userPhoto->getName()]['name'];

}

}

Comment out or delete bellow lines that are related to CAPTCHA. You can comment the code out using /* code that needs to be commented out here */ :

- /*$captchaField = new CaptchaField('captchaField'); $this->addElement($captchaField);*/

- /*{ $captchaField->setValue(null);*/

- /*}*/

If you are commenting out the code, you will get following as a result:

Save edited file. Now all you need to do is to remove CAPTCHA block from .html files.

2. Disable CAPTCHA in .html files

 Note: make a copy of the join_index.html file before you start editing and save the copy, for example on your desktop. In case of any issues use saved copy to reverse incorrect changes.

Go to ow_systemplugins/base/views/controllers →find join_index.html→open this file in editor you are comfortable with →find following piece of code:

<tr><th colspan="3">{text key="base+questions_section_captcha_label"}</th></tr>

<tr class="{cycle name=captchaField values='ow_alt1,ow_alt2'}" >

<td colspan="3" class="ow_center">

<div style='padding:10px;'>

{input name='captchaField'}

<div style="height:1px;"></div>

{error name='captchaField'}

</div>

</td>

</tr>

Comment the code above using {* code here *} or delete it. Here is how the code will look like if you are commenting it out:

{* <tr><th colspan="3">{text key="base+questions_section_captcha_label"}</th></tr>

<tr class="{cycle name=captchaField values='ow_alt1,ow_alt2'}" >

<td colspan="3" class="ow_center">

<div style='padding:10px;'>

{input name='captchaField'}

<div style="height:1px;"></div>

{error name='captchaField'}

</div>

</td>

</tr> *}

Save edited file and check whether changes were applied on your site.

Note: Please remove CAPTCHA code BOTH from join.php and join_index.html files. Editing only one of those files will cause errors on your site

IF YOU UPDATE THE SOFTWARE ALL CHANGES WILL BE LOST AND YOU WILL HAVE TO DO THEM ONCE MORE.

Everything becomes unclickable.

Meaning, you can't click on the username, email, password, etc (on the join form) to edit them and to join.

give for me 

Error 500

Internal Server Error.

$this->setEnctype('multipart/form-data'); /*$captchaField = new CaptchaField('captchaField'); $this->addElement($captchaField);*/ $controller->assign('display_photo', $displayPhoto); $controller->assign('display_terms_of_use', $displayTermsOfUse); if ( OW::getRequest()->isPost() ) /*{ $captchaField->setValue(null);*/ if ( isset($userPhoto) && isset($_FILES[$userPhoto->getName()]['name']) ) { $_POST[$userPhoto->getName()] = $_FILES[$userPhoto->getName()]['name']; } /*}*/ }

and

{text key="base+questions_section_captcha_label"}

{input name='captchaField'} {error name='captchaField'}
