Error found : StartTag: invalid element name in must_have_module_list.xml file.

[Mila]

Hi,

I did migration of website and since then I do have this error message in my BackOffice every time I login: Error found : StartTag: invalid element name in must_have_module_list.xml file.

I did clean cache, checked permissions of this file and carpet where it´s allocated, deleted the must_have_module_list.xml file in public html/config/xml and the message didn´t disappear.

Also I tried replace this file by old one which I had before migration and it didn´t work as the system generates new one with error.

Can anybody help with this?

Thank you.

I would suggest reporting the issue to Prestashop via their forge system.  if you open the xml file in question, you will see that the file contents contain html content with a 301 redirect.  This means Prestashop backend server is not working properly.

I had same error. Problem was from 

pm_advancedtopmenu

module. There is in pm_advancedtopmenu.php function, that changing xml file. 

private function _MHM_update() {
  if ($this->_MHM_needUpdate()) {
    $this->initClassVar();
    $content = file_get_contents(_PS_ROOT_DIR_.Module::CACHE_FILE_MUST_HAVE_MODULES_LIST);
    if (strlen($content) == 0) $content = '<?xml version="1.0" encoding="UTF-8"?><modules></modules>';
    $new_content = Tools::file_get_contents('http://www.presta-module.com/cross-selling-addons-modules-footer?xml=1&iso='.$this->_iso_lang.'&pm='.$this->_getPMdata());
    if ($new_content !== false) {
      $content = str_replace('<modules>', '<modules><!-- PM_MODS -->'.$new_content.'<!-- /PM_MODS -->', $content);
      @file_put_contents(_PS_ROOT_DIR_.Module::CACHE_FILE_MUST_HAVE_MODULES_LIST, $content);
    } else {
      $content = str_replace('<modules>', '<modules><!-- PM_MODS --><!-- /PM_MODS -->', $content);
      @file_put_contents(_PS_ROOT_DIR_.Module::CACHE_FILE_MUST_HAVE_MODULES_LIST, $content);
    }
  }
}

For fix it, we need to change link from "http://..." to "https://..."
