include a 'Shop System' static template file (from extensions)
never use the 'Shop System Test' or the 'plugin.tt_producs [DEPRECATED]'
set 'in stock' greater 0 for the products and articles
do not use languages or have products in the products alternative languages tables
the shop template file is found
an error in the shop produces an entry in the PHP error_log file (activate this in Install Tool and php.ini)
the cache has been cleared before
set the pid_list and recursive in TypoScript or set the startingpoint/recursive inside of the shop plugins
If you make an update with the Extension Manager from an older version of tt_products and did not install the Table Library 'table' and FEBE Library 'fh_library' before that, you will end up in the error message TYPO3 Fatal Error: Extension key "table" was NOT loaded! (t3lib_extMgm::extPath)Steps to undo the TYPO3 fatal error:
1. edit typo3conf/localconf.php
2. remove the tt_products entry
3. delete the temp_CACHED_ files in typo3conf
4. press reload from the browser
Please look at the website http://wiki.typo3.org/index.php/Ext_tt_products .
Get the latest development version at http://ttproducts.de
.htaccess must be properly configured otherwise tt_products doesn't work as expected because the plugin can't find all necessary scripts with poor configuration of .htaccess.
Wrong parameters, GET/POST var 'tx_ttproducts_pi1[product]' was missing or no product with uid = 0 found.You should set the PIDitemDisplay to inform the shop how the link parameter 'tx_ttproducts_pi1[product]' to the single view shall be generated.
Pay attention to all legal claims of all the countries to where you send goods!
