Common behaviour and list of (error) messages that might occur
===Description===
Tag extensions, like FlexForm, cannot hold any html in its arguments.<syntaxhighlight lang="html">
<_input type="text" value="hello<br>how are you" />
</syntaxhighlight>The above example will simply not be rendered. This is how MediaWiki tags work.

You can use the following syntax, it at least will not break. It is another way of writing tag code.<syntaxhighlight lang="html">
{{#tag:_input||type=text|value=hello<br>how are you}}
</syntaxhighlight>The HTML will be filtered out. '''However, with the new Parsoid Parser that is introduced, do not use the <nowiki>{{#tag:}}</nowiki> method anymore.''' It will give unpredictable results as Parsoid renders these tags in no particular order.

Here's a list of common error messages that might occur, with a brief description of what the problem might be.

|Make sure you set the FlexForm config : <code>$wgFlexFormConfig['file_temp_path'] = "";</code>
to a path where FlexForm has write rights. If you leave this empty, FlexForm will try to temporarily store the uploaded files in its own extension folder in the uploads folder. You can also check to see if this folder has write rights.

=== Error messages in the browser's console ===

{| class="table"
|-
| <code>Uncaught (in promise) ReferenceError: wgFlexFormSecure is not defined</code> (FlexForm.general.js)
| JavaScript error. This message may show if you forgot to set <code>$wgParserCacheType = CACHE_NONE;</code> in your LocalSettings.php file. Some features, such as instances, may not work without it.
|-
| <code>Uncaught SyntaxError: redeclaration of let ffDecryptObj</code> (FlexForm.general.js)
| JavaScript error. Same as above.
|-
| <code>SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data at line [...] column [...] of the JSON data</code> (FlexForm.general.js)
| This may happen if you have set your config options for debugging in such a way that any PHP warnings are printed, in turn mangling the JSON output expected by FlexForm. It is generally not a good idea to permanently use settings like <code>ini_set( 'display_errors', 1 ) </code> or <code>error_reporting( E_ALL )</code> in a live environment.
