Hitting a wall with installation : blank screen

[lhungil]

Looks like the server has XCACHE installed. Replace the original "/zc_install/index.php" from Zen Cart 1.5.4.

Then (based on the output from phpinfo) open up "/zc_install/index.php" and change the following lines.

FROM:

if (function_exists('apc_clear_cache')) @apc_clear_cache();
//XCACHE
if (function_exists('xcache_clear_cache')) @xcache_clear_cache();
//EA

TO:

if (function_exists('apc_clear_cache')) @apc_clear_cache();
//XCACHE
if (function_exists('xcache_clear_cache')) {
  @ini_set('xcache.cacher', 'OFF');
}
//EA

And try the installation again with the changes above.

Given all the difficulties you've had with importing the database, I'm inclined to ask: who's the hosting company?
Don't they provide standard tools like phpMyAdmin to manage database data?

Read MY MIND.. because MY thought was that it sounds like it time for the OP to find a NEW hosting company.. Sounds like their server setup was the end and beginning of the OPs issues.. (IJS...)

Could be their OLD hosting provider had really old versions of PHP and MySQL... And the database export contained "TYPE=MyISAM" instead of "ENGINE=MyISAM"... I've not tried importing old mysqldump code into a newer version of MySQL using a recent version of phpMyAdmin, so just speculating...

But at the same time... Why did the NEW hosting provider change the credentials on the database without notifying you?

I also did not like the answer of "just use the installation front controller (index.php) from an older version to install the current version of Zen Cart"... Granted this one was probably a little more difficult to troubleshoot... But once the OP posted the PHP information (and I saw XCache installed), I found the answer by doing a quick search of these forums with "install blank page XCache " (and then did another search to find a potential way to temporarily disable OP code caching via XCache during the Zen Cart installation)...

and hence yet another RECENT example on this forum on WHY OH WHY you DO NOT go to your hosting company to troubleshoot Zen Cart, WordPress, Joomla, Drupal, etc issues.. They USUALLY just AREN'T the right folks to ask..
