**solved** blank page and modules not installed **solved**

[vincentdenkspel]

Hi all,

I've installed Prestashop. After installing I can access the backend.
However, the modules are not visible in the backend.

I also get a blank page when I visit the frontend.

Does anybody have an idea what I did wrong and how I can resolve this ?

Thank you in advance.

Best regards,
Vincent


UPDATE:

After setting 'display_errors, 'Off); to 'On' I got the following message:

Fatal error: Call to undefined function mb_convert_encoding() in /home/ertee/public_html/classes/Tools.php on line 1524

This message was displayed on the front page as well as in the module section of the back end.

The line is:

$filename = mb_convert_encoding(md5(strtoupper($filename)),"UCS-4BE",'UTF-8');

Can anybody explain to me what this means an I this problem can be resolved.

Thanks.

UPDATE 2

For other people with the same problem:

To solve this you need to install/compile php_mbstring
Once this was done everything was ok.

Hi,

Could you share how to install php_mbstring? I installed php and apache locally on my windows machine. Thanks.

Ok, figured out the fix.

In php.ini, uncomment the line

extension=php_mbstring.dll

Then restart apache. That's it. Fixed my problem.

I changed the php.ini, as instructed, still with the same error can you help me?

[vincentdenkspel]

Sorry, I can't help you.
I've a managed hosting account so I asked the provider to do his for me.

[Valdivino]

Would not someone who has gone through this situation that can help me.

The situation after I installed the version 1.4.17, and this production has shown the following error.


PHP Fatal error: Call to undefined function mb_convert_encoding () in / home / xxxxxx / public_html / classes / Tools.php on line 1524.

I'm hosting on dedicated server CentOS 5 with cPanel / WHM.

I am using Prestashop 1.4.17 in WHM. I face the same problem.
I have installed mb_string module in apache http.config file.
Everything worked fine for me. To install mb_string in WHM,
1) Login WHM, you will find EASYAPACHE (APACHE UPDATER) on left side under software tab.
2) After selection you will be promted with different steps to configure apache.go through and in step 6 you will find the list of installed modules with check boxes checked.
3) Select the mb_string and build the apache.

Thank You
Bharadwaj.
