civiCRM有时候会报出下面错误，为什么吗？

nitialization Error

Array
(
    [callback] => Array
        (
            [0] => CRM_Core_Error
            [1] => simpleHandler
        )

    [code] => -14
    [message] => DB Error: no database selected
    [mode] => 16
    [debug_info] => SELECT locale_custom_strings FROM civicrm_domain WHERE id = 1 [nativecode=2027 ** Malformed packet]
    [type] => DB_Error
    [user_info] => SELECT locale_custom_strings FROM civicrm_domain WHERE id = 1 [nativecode=2027 ** Malformed packet]
    [to_string] => [db_error: message="DB Error: no database selected" code=-14 mode=callback callback=CRM_Core_Error::simpleHandler prefix="" info="SELECT locale_custom_strings FROM civicrm_domain WHERE id = 1 [nativecode=2027 ** Malformed packet]"]

google地图分三个
1. google.cn的 http

http://ditu.google.cn/maps/api/js
这个不会被墙，且加载的资源都是.cn 的，最好用，但是要求你的域名也是http的
如携程http
http://hotels.ctrip.com/international/bangkok359 能够正常展示
但是无法使用google.maps.places.Autocomplete 地址搜索接口（此接口依然走的google.cn）
2.google.cn 的https

https://ditu.google.cn/maps/api/js
这个js正常但是，资源用的是.com

例如携程的地图如果用https访问的话效果如下
https://hotels.ctrip.com/international/bangkok359 无法正常展示

这里写图片描述
3. google.cn

https://ditu.google.cn/maps/api/js 除非翻墙，否则彻底没戏
总结

彻底放弃google

Let’s remove Google map from this page:

1. Connect to your FTP or File Manager and follow this path “templates\themeХХХХ\html\com_contact\contact\default.php” to open “default.php” file:

   

2. In default.php file search for this code:

   ?

   1 2 3 4

   <!-- Map -->   <div class="contact_map" id="contact_map">   {mosmap}   </div>

   

3. Remove those codes and hit Save changes.

4. Refresh the page to see that the google map has been removed:
