I have come across with some errors in my website and I contacted my hosting provider and they said that it's not a web server issue. This is the response by my hosting provider.
Here is the error:
[18-Oct-2013 04:55:53] PHP Catchable fatal error: Argument 1 passed to aPage_Modules::link Text() must be an array, null given, called in /hsphere/local/home/intellig/xxxxxxxxx.com.au/catalog/includes/modules/ultimate_seo_urls5/page_modules/product_info.php on line 170 and defined in /hsphere/local/home/intellig/xxxxxxxxx.com.au/catalog/includes/modules/ultimate_seo_urls5/abstracts/page_modules.php on line 338
The issue will be related to the mod_rewrite rules in the .htaccess, or the settings in the ultimate_seo_urls5 plugin.”
Anyone can help me figure out what should be done to correct this problem?
