The latest version of Textpattern CMS, 4.5.5 as I write this, trips up on PHP 5.5. In my previous post I explained how to solve the `yield` error that is thrown up with Textpattern 4.5.5 and PHP 5.5, and this article is in a similar vein. If you run Textpattern 4.5.5 alongside PHP 5.5, you will likely see this error at some stage:
Internal error “preg_replace(): The /e modifier is deprecated, use preg_replace_callback instead”
Note that the error will occur only in the admin-side of Textpattern, your users will not be shown a bewildering error and be scared off. Additionally, the error will be thrown up when the following criteria are met:
- the site is in Testing or Debugging mode
- an article is posted or updated
The culprit in this case is Textile, the markup generator baked into Textpattern. When sporadic reports of this problem were reported in late 2013, a fix was created and Textile was updated to resolve the problem. As such, the solution to the `preg_replace` error is to drop in the updated Textile file from the issue tracker here. When this file is replaced with the updated version, the `preg_replace` errors will no longer appear.
