you don't have the php mbstring extension installed. What version of opencart are you using? I thought all the mbstring stuff was supposed to be removed from the latest one, though to be honest all decent hosts should have the mbstring functions loaded.

Assuming you are using 1.5.1.3

there was one mb_string function left in by mistake - Daniel swore at me when I told him lol

Fixed in SVN, but basically edit catalog/controller/product/category.php

find change to the favicon.ico is something your browser is trying to fetch invisibly, so don't worry about that unless you want to upload one to the root

the robots.txt one is either the same scenario as the favicon.ico above or you have specified in your .htaccess something to do with maybe blocking access to robots.txt for non-bots

i got it working! thanks for your help

Hi, I have the same problem as above,

'description' => mb_substr(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8')), 0, 100) . '..',

I have changed it as mention
'description' => utf8_substr(strip_tags(html_entity_decode($result['description']), 0, 100) . '..',

However, now on line 192,195.196 and 198 I am getting some errors, when change the next error is;


Parse error: syntax error, unexpected T_DOUBLE_ARROW in public_html/catalog/controller/product/category.php on line 192

Any Idea how to fix this. I am using the latest version of oc

You can add a second closing brace after the $result['description] since it's missing or just save this file
http://opencart.googlecode.com/svn/trun ... tegory.php
to your server under /catalog/controller/product/category.php

I checked and mb-string was not enabled on my php install. I have Fedora 16 so I ran the following:
sudo yum install php-mbstring

Then restarted apache:
sudo systemctl stop httpd.service
sudo systemctl start httpd.service

Site is working great!
Thx

ah nice one! Glad its all working again!

i don't know coding. can anyone help me in a simplest way step by step? this is bothering me like anything, and stopping my website to get published !

Many thanks,
Balram

First time posting, sorry if its in the wrong place.

I am having a similar problem. After a clean install of 1.5.2.1, everything was working fine until I restored my database. Now the product pages are blank. Everything else shows up perfectly, except any of the product pages.


Here is the server error I am getting.

2012-03-23 11:58:02 - PHP Notice: Error: Unknown column 'sort_order' in 'order clause'<br />Error No: 1054<br />SELECT * FROM product_image WHERE product_id = '80' ORDER BY sort_order ASC in /Library/Server/Web/Data/Sites/am/system/database/mysql.php on line 49

2012-03-23 11:48:53 - PHP Notice: Undefined index: count in /Library/Server/Web/Data/Sites/am/admin/view/template/module/category.tpl on line 65

Any help would be greatly appreciated.
