Problem med class.fastTemplate
HejJeg får denne fejl i en af mine scripts efter at have reinstalleret min apache server og php:
Fatal error: Cannot redeclare clear_parse() in C:\Program Files\Apache Group\Apache2\htdocs\projektstyring\inc\class.FastTemplate.php on line 635
Det virkede før at jeg reinstallerede.
Her er indholdet af min class.fastTemplate:
