I try you point out enable error got follow information:

5 Out of memory (Needed 4194276 bytes)
in:
[select count(distinct p.products_id) as total FROM (new_products p LEFT JOIN new_manufacturers m USING(manufacturers_id), new_products_description pd, new_categories c, new_products_to_categories p2c ) LEFT JOIN new_meta_tags_products_description mtpd ON mtpd.products_id= p2c.products_id AND mtpd.language_id = 1 WHERE (p.products_status = 1 AND p.products_id = pd.products_id AND pd.language_id = 1 AND p.products_id = p2c.products_id AND p2c.categories_id = c.categories_id AND ((pd.products_name LIKE '%socket%' OR p.products_model LIKE '%socket%' OR m.manufacturers_name LIKE '%socket%' OR (mtpd.metatags_keywords LIKE '%socket%' AND mtpd.metatags_keywords !='') OR (mtpd.metatags_description LIKE '%socket%' AND mtpd.metatags_description !='') OR pd.products_description LIKE '%socket%') ))]

What is that mean?

[diytools]

It is that server memory problem?

[DrByte]

Yes, it is probably a memory problem with the PHP configuration.

Go to Admin->Tools->Server Info. What does it show for PHP Memory Limit?

For most stores 32M is sufficient, but most of the time server administrators configure it to at least 128M nowadays.

For most stores 32M is sufficient, but most of the time server administrators configure it to at least 128M nowadays.

Actually, most servers are using a PHP Memory Limit of 256MB these days and is a mandatory min. for servers using cPanel.

Speaking of which, you are probably familiar with how WordPress allows one to determine memory limit usage in the "default-constants.php" file. Does Zen Cart have such a setting?

No. Given that Zen Cart's needs are so low it's rare to have a legitimate memory issue unless you're using a very badly configured server, in which case you've got even bigger problems.
One exception is if you're running specific batch scripts (that aren't part of Zen Cart) that don't release memory well; in that case you can set the memory limit yourself during those scripts ... and probably should set execution time too.

But, if you really want a file to set it in for yourself, feel free:
/includes/extra_configures/custom_memory_limit.php

@ini_set( 'memory_limit', '256M' );

Just remember that this overrides whatever you've set in your hosting company's control panel PHP preferences, so now you have "yet another" place to have to check when troubleshooting things.
