Tmd Product import export - Error while trying to click Import link

I can very well export file without any error. But, I am getting following error while clicking Import, quick help will be appreciated.

Fatal error: Uncaught Exception: Error: Could not load model extension/import! in /home/myang/public_html/vqmod/vqcache/vq2-system_storage_modification_system_engine_loader.php:97 Stack trace: #0 /home/myang/public_html/vqmod/vqcache/vq2-admin_controller_extension_import.php(64): Loader->model('extension/impor...') #1 /home/myang/public_html/vqmod/vqcache/vq2-system_storage_modification_system_engine_action.php(79): ControllerExtensionimport->index() #2 /home/myang/public_html/admin/controller/startup/router.php(26): Action->execute(Object(Registry), Array) #3 /home/myang/public_html/vqmod/vqcache/vq2-system_storage_modification_system_engine_action.php(79): ControllerStartupRouter->index() #4 /home/myang/public_html/vqmod/vqcache/vq2-system_storage_modification_system_engine_router.php(114): Action->execute(Object(Registry)) #5 /home/myang/public_html/vqmod/vqcache/vq2-system_storage_modification_system_engine_router.php(103): Router->execute(Object(Action)) #6 /home/myang/public_html/system/frame in /home/myang/public_html/vqmod/vqcache/vq2-system_storage_modification_system_engine_loader.php on line 97

Get with the extension developer to figure this out (but looks like you are missing a file: Could not load model extension/import).

Check for the existence of the file admin/model/extension/import.php .

Uploading the files again sorted.

But the export of files takes much time and receiving "The page requested was not found"...

I want to export 5000 products to update price changes.

max_execution_time = 60
memory_limit = 64M

Looks like a timeout error. You may have to get in touch with the author of that extension. Or try to restrict the number of exported products, using batches smaller than 5000.

Updating less than 500 sometimes working sometimes showing error,

any help on this

You really need to contact the author of this extension for this which I think is ashwani_multi.
