Hi Jonathan - can you please supply some sample code - it will make it easier for people to test etc.

Also resetting the priority according to https://docs.joomla.org/Priority

Thanks Brian.

Here is the module xml file that is causing the initial issue. Basically any module with multiple textarea or editor field types.

I cannot confirm/replicate for J!3.4.1 and Staging (2015-04-05).

I made some tests with several core modules where I added something like this in XML file (2 editors, 2 textareas).

...
    <customContent />
    <config>
 <fields name="params">
  <fieldset name="basic">

<!--ADD THIS-->
<field name="articletext" type="editor"
label="articletext"
filter="JComponentHelper::filterText" buttons="false" />

<field name="articletextarea" type="textarea"
label="articletextarea" />

<field name="articletext2" type="editor"
label="articletext2"
filter="JComponentHelper::filterText" buttons="true" />

<field name="articletextarea2" type="textarea"
label="articletextarea2" />
<!--/ADD THIS-->
...

Then I copied your whole CONFIG block to core modules. Also no problems. All fields were saved correctly.

Hello,

I am facing the same problem and i have 5 editor fields in custom module params and i have few text boxes fields, After filling the content in Editor and make it save then value of all the fields get blank/clean.

It is working on localhost but when i upload on the server then it doesn't work. Please help to resolve the issue.

Regards,
Anamika

Hey @anamikakush we're still having this issue ourselves, but only on some sites in some instances. Even different sites on the same server are having issues—some work and others do not.

I'm not sure what it could be and we're still trying to exactly pin-point it ourselves.

@webmonkiee please check your php error logs on the sites where it fails for any error message about max_input_vars

It is several months since the request for further information which has not been provided. I am closing this at this time - it can always be re-opened
