Hello Reena, to remove the tags field go to wp-content/plugins/geodirectory and open the file geodirectory_template_actions.php.
you need to comment this block, from
<div id="geodir_post_tags_row" class="geodir_form_row clearfix" >
<label><?php echo TAGKW_TEXT; ?></label>
<input name="post_tags" id="post_tags" value="<?php echo esc_attr(stripslashes($kw_tags)); ?>" type="text" class="geodir_textfield" maxlength="<?php echo TAGKW_TEXT_COUNT;?>" />
<span class="geodir_message_note"><?php echo TAGKW_MSG;?></span>
</div>
to
<!-- <div id="geodir_post_tags_row" class="geodir_form_row clearfix" >
<label><?php echo TAGKW_TEXT; ?></label>
<input name="post_tags" id="post_tags" value="<?php echo esc_attr(stripslashes($kw_tags)); ?>" type="text" class="geodir_textfield" maxlength="<?php echo TAGKW_TEXT_COUNT;?>" />
<span class="geodir_message_note"><?php echo TAGKW_MSG;?></span>
</div>-->
(basically adding <! – – before and – – > after)
Side effect:you need to do that each time when a GD update will be released.
