I have migrated my magento from 1.8.x to 1.9.3 but after that magento product image browse file button is not working, if I click browse button it doesn't do anything.
in console I can see error like
Uncaught ReferenceError: Uploader is not defined(…)
I can see already existing images and working fine in both admin and front end.
Try this,
Please check this file available or not
/skin/adminhtml/default/default/media/uploader.swf /skin/adminhtml/default/default/media/uploaderSingle.swf /skin/adminhtml/default/default/media/editor.swf /skin/adminhtml/default/default/media/flex.swf /app/design/adminhtml/default/default/template/media/uploader.phtml /app/design/adminhtml/default/default/template/media/editor.phtml
This might be due to the Uploader module not being recognized. Try flushing your configuration cache (System > Cache Management or rm -rf var/cache/*).
Make sure following files are in place and readable by the webserver – try retrieving their URLs directly to see if this is the case:
js/lib/uploader/flow.min.js
js/lib/uploader/fusty-flow-factory.js
js/lib/uploader/fusty-flow.js
js/mage/adminhtml/uploader/instance.js
Ensure file app/design/adminhtml/default/default/layout/main.xml contains
<action method="addJs"><name>lib/uploader/flow.min.js</name></action>
<action method="addJs"><name>lib/uploader/fusty-flow.js</name></action>
<action method="addJs"><name>lib/uploader/fusty-flow-factory.js</name></action>
<action method="addJs"><name>mage/adminhtml/uploader/instance.js</name></action>
If this is the case, flush your layout cache and especially delete your merged JS & CSS file cache (lower left at System > Cache Management).
