@sauvagere : It seems that you solved your problem , it would be good for others to describe your solution , thank you
@:Jost : you are using custom template for comment (I'm not familiar with mod pack but it could be it's template engine) and plugin couldn't find your comment block to replace , you have 3 way to solve this problem :
1)Copy & past original comment template form original CPG's themes.inc.php (not modpack) to your theme.php
something like this
// HTML template for the form to add comments
if (!isset($template_add_your_comment)) //{THEMES}
$template_add_your_comment = <<<EOT
<form method="post" name="post" action="db_input.php">
<table align="center" width="{WIDTH}" cellspacing="1" cellpadding="0" class="maintable">
<tr>
<td width="100%" class="tableh2_compact"><b>{ADD_YOUR_COMMENT}</b></td>
</tr>
<tr>
<td colspan="1">
<table width="100%" cellpadding="0" cellspacing="0">
<!-- BEGIN user_name_input -->
<tr>
<td class="tableb_compact">
{NAME}
</td>
<td class="tableb_compact">
<input type="text" class="textinput" name="msg_author" size="10" maxlength="20" value="{USER_NAME}" />
</td>
<!-- END user_name_input -->
<!-- BEGIN input_box_smilies -->
<td class="tableb_compact">
{COMMENT}
</td>
<td width="100%" class="tableb_compact">
<input type="text" class="textinput" id="message" name="msg_body" onselect="storeCaret_post(this);" onclick="storeCaret_post(this);" onkeyup="storeCaret_post(this);" maxlength="{MAX_COM_LENGTH}" style="width: 100%;" />
</td>
<!-- END input_box_smilies -->
<!-- BEGIN input_box_no_smilies -->
<td class="tableb_compact">
{COMMENT}
</td>
<td width="100%" class="tableb_compact">
<input type="text" class="textinput" id="message" name="msg_body" maxlength="{MAX_COM_LENGTH}" style="width: 100%;" />
</td>
<!-- END input_box_no_smilies -->
<td class="tableb_compact">
<input type="hidden" name="event" value="comment" />
<input type="hidden" name="pid" value="{PIC_ID}" />
<input type="submit" class="comment_button" name="submit" value="{OK}" />
</td>
</tr>
</table>
</td>
</tr>
<!-- BEGIN smilies -->
<tr>
<td width="100%" class="tableb_compact">
{SMILIES}
</td>
</tr>
<!-- END smilies -->
</table>
</form>
EOT;
2)Edit plugin's codebase.php file and change reg. expression
3)Use Captcha MOD instead of this plugin
@Kapitan_Pirula :I've got this when I browse
captcha.phpFatal error: Call to undefined function: imageftbbox() in /home/html/galeria/plugins/captcha/include/captcha.class.php
It says that you don't have one of php's function (
imageftbbox) installed, probably your host disable it , ask for support from host
