Usage/Installation Instructions

Install this update via the menu Extras > Installer in the MODX manager. Clear your MODX cache, by clicking the menu Manage > Clear Cache. A new tab in your resource-edit panel will appear called 'SEO'.

First of all: ALWAYS MAKE A BACKUP BEFORE UPDATING! Especially the modx_site_content database table in this case.

Upgrading to 2.0.0 from 1.* is highly recommended, but it does introduce some risks. SEO Tab 1.* stored the 301 redirects into the properties-column of a resource. SEO Tab 2 stores it in a seperate database table. This means a migration is needed. The migration-process is memory-intensive and might take a very long time, so just let it roll until it mentions a finished migration.

Possible problems (and solutions):

  • Long migration-process because of many resources and redirects (think of 1000+ resource websites). Not really a problem, but if you have a big site, just plan your update at a low-traffic time, because redirects won't work 100% during the migration.
  • A blank page with a 500 error. This usually is because of memory issues. Try to re-run the migration with a lower limit and queryLimit. It is currently set to limit:1000 and queryLimit=100. Try setting it to 500 and 50 in core/components/stercseo/processors/mgr/redirect/migrate.class.php
  • If you somehow end up with an unfinished migration and the migration-notice is gone, you can fix it by setting the SystemSetting stercseo.migration_status to 0.
