Why isn't my PHP initialization file taking effect?
A PHP initialization file is not always immediately recognized by shared hosting accounts' servers. Here are tips for making sure it does take effect.
Things to Check
- Make sure you're using the correct filename (more info).
- Understand your PHP initialization file's refresh rate:
Filename Refresh Rate
Only updates when a new PHP process is created, e.g. when a new visitor comes to your site. However, refreshing your own site you recently visited does not generate a new PHP process.
By default, updates every 5 minutes
- Try getting the server to recognize the updated file. Which process you use depends on your hosting account's operating system (more info).
