Pursuing a dream appeared backstage 500 error performance
Pursuing a dream 500 internal server error is usually small partner iis environment will encounter, weaving dreams of 500 error is usually because these two causes
The first 500 Cause: Pursuing a dream version of your site that you host PHP version is too low to too high
1, first check your web application version of what is weaving dreams
Open /data/admin/ver.txt file viewing, such as
2014, 2015, 2016, 2017 beginning belong to the old version
2, and then check your host PHP version
The easiest way to see it of course is to look in your host panel
If you do not see the host panel, you can add your own a p.php, which marked the code
<?php
phpinfo();- 1
- 2
Figure
The p.php upload the file to the root directory of your site, and then open in a browser
http: // domain /p.php
As shown, you can see it php version currently used by the host, after reading it, remember to delete this file p.php oh.
Pursuing a dream after watching the host PHP version and version
2014, 2015, 2016, beginning of 2017 weaving dreams versions of the older version low version
Is not running at more than PHP5.4 PHP5.5 version of the environment
In this case, the solution
Either the PHP version reduced to PHP5.2 normal use dedecms low version of the program, or upgrade to the latest weaving dreams program version 20180109
The second 500 error reasons: weaving dreams weaving dreams core file is missing or core file error codes
This case is difficult to find a specific cause of which file, I personally recommend that you use an alternative method to solve
You put these three files on the Web site as a backup folder renaming
dede (background) renamed as a backup dede1
renamed as a backup data data1
include include1 renamed as a backup
From weaving dreams weaving dreams official download and unzip the package, the three official program files folder uploaded to bag up your site
And then just renamed data1 / common.inc.php and data1 / config.cache.inc.php back into the new data folder on it
