### 日志报错追踪：
  * Columns Plugin
  * Doodle4 Plugin 
  * Gallery Plugin 
  * imgpaste plugin 
  * [[target=blank|https://www.dokuwiki.org/plugin:targetlink|targetlink]]

\\

result:
  - E_WARNING: Undefined property: syntax_plugin_targetlink::$schemes
/storage/lib/plugins/targetlink/syntax.php(197)
  - 页面中将target=blank 改成 target=_blank 会导致targetlink pluging的错误日志产生,继续测试[[target=_blank|https://wiki.bjzl.net.cn/test1|报错]]
  - E_WARNING: Array to string conversion/var/www/html/inc/parser/metadata.php(620) 
  - 看上去是plugin\gallery\ 导致的,试关闭gallery


[[page1|This link]] opens in the same tab

but [[+tab|page2|this one]] opens in the new tab,

and so does [[target=_blank|page2|this one]]，
