[Solved] Javascript error (parseJSON) detected for action "upgradeNow". Starting restoration...

[LucianoNapoli]

Trying updating from 1.5.4.1 to 1.5.5 I got this error "Javascript error (parseJSON) detected for action "upgradeNow". Starting restoration...

To solve the error follow this steps:

 

1. Open file in modules\autoupgrade\db\Db.php

2. Go to line 212 and uncomment the lines

if (PHP_VERSION_ID >= 50200 && extension_loaded('pdo_mysql'))
$class = 'DbPDO';
else if (extension_loaded('mysqli'))
$class = 'DbMySQLi';

 

 

Don't forget to active mysqli and mysql pdo extensions.

Hi,

 

Well that sounds great and I will try that for sure but how exactly do I activate mysqli and mysql pdo extensions?

mysqli and mysql pdo extensions usually are activated by your hosting provider. You have to change the php.ini

[Vorwaerts]

Great, I will try to check with my phpinfo and then my provider, thanks!

My line 212 is different

 

public static function getClass()

{

$class = 'MySQL';

if (extension_loaded('mysql') && PHP_VERSION_ID < 50500)

$class = 'MySQL';

elseif (extension_loaded('mysqli'))

$class = 'DbMySQLi';

elseif (PHP_VERSION_ID >= 50200 && extension_loaded('pdo_mysql'))

$class = 'DbPDO';

return $class;

}

 

Yet I have the same error.

There is nothing to uncomment... :-( Still cannot upgrade due the same error...

What do you mean by " Don't forget to active mysqli and mysql pdo extensions.

?" could you please explain the steps how we do it?

Me too

I have solved it like this:

 

1. added the follow code on php.ini file

extension=pdo.so
extension=pdo_sqlite.so
extension=sqlite.so
extension=pdo_mysql.so
extension=mysqli.so

2. added the follow code on .htaccess file to include the php.ini file. Add it at the end or 1-click upgrade will cancel it

<IfModule mod_suphp.c>
suPHP_ConfigPath /home/yourfilepath/
<Files php.ini>
order allow,deny
deny from all
</Files>
</IfModule>

I hope it will help.
