[AbraKadaWeb]

Hi,

I just upgraded from 1.5.3.1 to 1.5.4.1 . but when I try to run upgrade.php I got this error:

Fatal error: Call to undefined function mcrypt_create_iv() in /var/www/vhosts/abrakadaweb.com/httpdocs/boutique/system/library/encryption.php on line 8

I have access to admin panel,

Somebody can help me on this please?

Thanks in advance

=================
I ran upgrade.php I think it was an error. Now I just ran intall.php and I see the ugrade instruction. But I have 3 line of error on top:

Notice: Undefined variable: dbuser in /var/www/vhosts/abrakadaweb.com/httpdocs/boutique/install/index.php(28) : eval()'d code on line 1

Notice: Undefined variable: dbpass in /var/www/vhosts/abrakadaweb.com/httpdocs/boutique/install/index.php(28) : eval()'d code on line 1

Notice: Undefined variable: dbname in /var/www/vhosts/abrakadaweb.com/httpdocs/boutique/install/index.php(28) : eval()'d code on line 1

I clic on UPGRADE, after when I refresh page and cleaned cookies twice on admin panet I lost the admin panel and got this error:(I replace my passwords by xxxxxx)

Notice: Error: Unknown column 'salt' in 'where clause'
Error No: 1054

I resume where I am now:

http://www.abrakadaweb.com/boutique/install/

I see this update page (see printscreen) What the best thing to do?

Additional information: I had a problem 1 months ago related mcrypt when I tried to install the following module: "OpenBay Pro-list, import & sync stock with eBay" My server does not support mcript . So I had to delete rows in the file index.php as directed officials of this extension. Everything was back to normal, but this extension is not VQMOD, files remained.

My website is down now, so if it is to complicated for now to fix, is somebody can tell me please how to roll back to 1.5.3.1?

thanks

you need to have the mcrypt php extension installed on your server

Thanks, but my provider said it is to complicated to install it...Is mcrypt needed to upgrade to 1.5.4.1?

yes, mcrypt is needed for v1.5.4.x
