May major release - Osclass 4.4.0 brings very important features and updates

It's been a while from time when Osclass 4.3 was released, today we bring you important updates and improvements of most favorite classifieds script. Open complete osclass changelog.

jQuery updated from 1.8 to 3.6

After 10 years, it is again possible to use latest jQuery version within Osclass. Once you upgrade to 4.4, you will be able to change jQuery version to latest (3.x.x) in Settings > General section. You should test your theme and plugins properly before using it in production, as libraries used in themes or plugin may not be compatible with jQuery 3.x.

Bulk actions are now supported on plugins page

Have you ever think about, how to disable 50 plugins at once, or how to search for particular plugins between 100 others? Until now, this was not possible and it required time consuming one-by-one updating of each plugin. Not anymore, important features has been created on plugin page, including bulk actions, search as well as layout & wording changes in plugin table.

Bulk actions you can now do with plugins:

  • Enable
  • Disable
  • Install
  • Uninstall
  • Delete

UX is very friendly and in case you want to i.e. enable plugin, that is already enabled, this plugin will be skipped and nothing happens to it.

Besides this, you can also search between plugins, where following fields are used in search:

  • Plugin name
  • Description
  • Version
  • Author

New section has been created in backoffice: Settings > Breadcrumbs, that allows you to customize breadcrumbs including:

  • content of breadcrumbs
    • Added option to disable/hide breadcrumbs on specific pages, including custom (plugin) pages
    • Added option to show all levels of categories on listing page
    • Added option to add country, region and city into breadcrumbs on listing page
  • visibility of breadcrumbs on different pages and sections

Frequently asked questions

Question: How do I switch Osclass 4.4 to jQuery 3.6 in Settings General?

Answer: Open Settings, General and select jQuery 3.6 after you upgrade to Osclass 4.4. Test the theme and plugins on staging first. Libraries written for jQuery 1.8 often break click handlers on 3.x. Leave 1.8 on production until that test passes. Check the browser console before you bulk-disable plugins.

Question: Why do Osclass plugins break after enabling jQuery 3 in 4.4?

Answer: Osclass 4.4 can load jQuery 3.6, but plugin scripts written for 1.8 use removed APIs. Reproduce on staging and read the console for the failing file, then disable that plugin. Bulk disable is an isolation step after you know it is a script conflict. You can switch jQuery back in Settings, General.

Question: How do I bulk disable plugins in Osclass 4.4 oc-admin?

Answer: Select many plugin rows in Osclass 4.4 and run bulk Disable after you have a failing page to compare. Already-disabled plugins are skipped by that bulk action. Search uses name, description, version, and author. Re-enable one at a time on staging. Do not bulk-disable production as the first jQuery 3 test.

Question: How do I hide breadcrumbs on a plugin page in Osclass 4.4?

Answer: Disable breadcrumbs on that custom plugin page in Settings, Breadcrumbs. Theme CSS cannot hide them if this setting still prints them. You can also add country, region, and city on listing breadcrumbs or show all category levels. Home and search are valid Exclude pages names too.

Question: Where does the Osclass 4.4 oc-admin color scheme apply including login?

Answer: Pick an oc-admin color scheme in Osclass 4.4 such as Default, Light, Modern, or Blue. The scheme applies to the whole backoffice including login. Omega uses it; Sigma and Zara on the front stay unchanged. Save Settings, then open the login screen in a private window to confirm.

Question: What do DEMO_THEMES and DEMO_PLUGINS do in Osclass 4.4 config.php?

Answer: Define DEMO_THEMES and DEMO_PLUGINS in config.php only on a demo so you can lock or showcase OsclassPoint products. Omit them on a live classifieds site. They are not jQuery or breadcrumb settings. A missing constant on production is expected. Do not copy demo defines onto a paying catalog.
