I got vQmod 2.3.2 to install successfully on a fresh install of opencart 1.5.5.1 with a renamed admin folder, according to the success message.
But I think I am missing a vital step, as my vqcache folder remains empty. I have searched the forums and Google but cannot find a fix that works.
Here is what I did:
1) Installed opencart 1.5.5.1
2) Renamed the admin folder and updated all instances in admin/config.php
At this stage everything works fine.
3) Uploaded vQmod 2.3.2 opencart
4) Set permissions for vqmod/vqcache, admin/index.php, and index.php to 755
5) Edited the vqmod/install/index.php folder to the new name on lines 50 and 86:
if(!is_writeable($opencart_path . 'mynewadminname/index.php')) {
$write_errors[] = 'Administrator index.php not writeable';
}
// Rename the admin part of the text below if you've
// changed your admin folder name
$u->addFile('mynewadminname/index.php');
6) Edited the vqmod/pathReplaces.php with my new admin name:
$replaces[] = array('~^admin\b~', 'mynewadminname');
7) Edited the vqmod/vqmod.php – line 54 – changed ‘include_once’ to ‘include’:
if($replacesPath) {
include($replacesPath);
$this->_lastModifiedTime = filemtime($replacesPath);
}

At this stage I got the success message and my store homepage seems fine.
But when I check my vqmod/vqcache folder it is empty?
Could somebody please advise me on how to make this work?
Thanks,
Dr M
