Ошибка в BladeCompiler
0
Доброго времени суток. После установки Laravel 5.1 столкнулся со следующей проблемой: при отображении сайта возникла ошибка: «ErrorException in BladeCompiler.php line 261:
preg_replace_callback(): Compilation failed: internal error: previously-checked referenced subpattern not found at offset 47» Система: Debian 7, PHP-5.5.25, PCRE Librery 8.36. И так решение проблемы
Открываем файл BladeCompiler.php, который находится в vendor/framework/src/illuminate/View/Compilers
