刚刚按照，感觉运行的好慢，但是可以正常运行；等吃个饭回来之后，就保存了，错误提示：

我修改 core_config_data 数据表里面的 dev/js/merge_files dev/css/merge_css_files dev/js/minify_files 三个 path 的 value 为 0 让后删除 /var 目录下面的所有目录，问题就不会出现了

Hey @leeyisoft, thanks for reporting this issue! Meanwhile could you please provide English equivalents for those non-latin phrases in your report? I am afraid I cannot understand the message completely because of parts of it reported in Chinese. Thank you!

Hi @verklov , I've just experienced the same error reported from @leeyisoft trying to activate globally configurations dev/css/merge_css_files, dev/css/merge_js_files, dev/js/minify_files

My local env is an Ubuntu 14.04 with Apache 2.4.7 with mod_php enabled with PHP 5.5.9-1ubuntu4.2 .

attached you can find the report
