Database Issues

Submitted by Retro135 on Mon, 2018-07-30 16:06 in

Hi David,
My InnoDB database bit the dust last week with. Installed newest version of mariadb, revised my.cnf. I had current PT and database table BUs. Have everything somewhat going again, but still have these errors which were present when mysql went down. Search, individual products, subsequent pages + these sections still display only blank pages:

{link saved}

The main / secondary category pages display the first page of results, show merchant & brand filter dropdowns and subsequent pages. If I select a merchant, brand, click a product or navigate to the next page, it's blank. When I view source, there's no content at all, no error code.

Displays fine:
{links saved}

I'm able to use import script and am importing individual merchants successfully.

How can this be fixed? Thank you!

Regarding the blank pages; to check for both PHP and / or database errors, if you could temporarily enable database debug mode by changing line 6 in config.advanced.php as follows;

  $config_databaseDebugMode = TRUE;

...but also, enable full PHP error reporting by adding the following lines to the end of config.advanced.php:


Then view one of the URLs returning a blank page again, and there may be a database and / or PHP error displayed. If there is and you're not sure from the output where the problem lies; or of course if there is no difference, let me know what (if anything) is displayed and I'll check it out further with you...

Cache cleared, all warnings displaying. This came up in the admin interface under Category Hierarchy Mapping:

Notice: Undefined variable: class in {path saved}/categories_hierarchy.php on line 110

line 110:
$sql = "SELECT DISTINCT(merchant) FROM `".$config_databaseTablePrefix."products` ORDER BY merchant";

Please could you email me admin/categories_hierarchy.php for reference and I'll follow this up with you...
