Modules tab wont show anything after manually upgrading

[mayid]

I upgraded from 1.3.5 to 1.3.6 manually. I mean, i installed 1.3.6 but then i override some tables: the categories and products ones more than all. See the list of tables i just overwrite:

    Line 455: DROP TABLE IF EXISTS `ps_image`;
   Line 494: DROP TABLE IF EXISTS `ps_image_lang`;
   Line 575: DROP TABLE IF EXISTS `ps_module`;
   Line 612: DROP TABLE IF EXISTS `ps_module_country`;
   Line 665: DROP TABLE IF EXISTS `ps_module_currency`;
   Line 686: DROP TABLE IF EXISTS `ps_module_group`;
   Line 706: DROP TABLE IF EXISTS `ps_product`;
   Line 771: DROP TABLE IF EXISTS `ps_product_attachment`;
   Line 789: DROP TABLE IF EXISTS `ps_product_attribute`;
   Line 822: DROP TABLE IF EXISTS `ps_product_attribute_combination`;
   Line 841: DROP TABLE IF EXISTS `ps_product_attribute_image`;
   Line 888: DROP TABLE IF EXISTS `ps_product_lang`;
   Line 957: DROP TABLE IF EXISTS `ps_profile`;
   Line 976: DROP TABLE IF EXISTS `ps_profile_lang`;
   Line 999: DROP TABLE IF EXISTS `ps_scene`;
   Line 1017: DROP TABLE IF EXISTS `ps_scene_category`;
   Line 1035: DROP TABLE IF EXISTS `ps_scene_lang`;
   Line 1054: DROP TABLE IF EXISTS `ps_scene_products`;
   Line 1076: DROP TABLE IF EXISTS `wp_options`;

In localhost it works just fine, but in remote host i found that the modules tab wont show a single thing. However, the positions area works fine.

I overwrite the modules tables as well because i was expecting to conserve my "old" configuration. How can i recover my pane?! It's important.

SOLVED. It was a memory issue. And i solved adding this line to config.inc.php

ini_set('memory_limit', '64M');

It also works with just 32M.

Cheers!
