I have a problem with Magento's backend. In Configuration, each multiselection field is empty, all options are no longer available. This problem is only in the configuration. Why?

I've already tried cleaning the cache and doing the reindex.

Any solution? Thank you

  • By each multiselection do you mean each currency dropdown or other dropdown (under other tabs) as well?

  • I created a new store in "manage store" with the website, store and store view. For store view i edited from database, I did the same procedure I always did. Does the problem depend on this?

I had the same issue and fold this solution

I looked at my file /httpdocs/app/code/core/Mage/Adminhtml/Block/System/Config

and matched it with original version

I was missing this line 463

here's a bigger chunk of the code to see full view the bolded area was missing from my file. I added it from original and it fixed it.

                if ($method) {
                    if ($fieldType == 'multiselect') {
                        $optionArray = $sourceModel->$method();
                    } else {
                        $optionArray = array();
                        foreach ($sourceModel->$method() as $value => $label) {
                            $optionArray[] = array('label' => $label, 'value' => $value);
                else {
                    $optionArray = $sourceModel->toOptionArray($fieldType == 'multiselect');
    return $this;
