## **Common Questions**

### **Common Question #1: Why am I getting a PHP Fatal Error while running wp commands?**

This error mainly occurs when the variables or database credentials specified in the **wp-config.php** file are wrong. [Check and update database credentials](https://www.nexcess.net/_categories/74176) and any variables set.

### **Common Question #2: Why am I getting wrong output due to the plugins or themes being used?**

Sometimes you may get different output than expected due to WordPress extensions (plugins, themes, must-use plugins, drop-ins).

You can resolve this by bypassing a single plugin or theme (**–skip-plugins=akismet**) or by skipping them entirely (**wp –skip-plugins –skip-themes**).

### **Common Question #3: Why am I have a Memory Exhausted Issue?**

By default, [sites hosted on Liquid Web will already have very high PHP default memory values set](https://www.nexcess.net/_questions/532668) and they should be enough.

You can [check out the default values here](https://www.nexcess.net/_questions/936158). However, if you face **Memory Exhaustion** issues, you can increase the **PHP** values by updating values in the **‘.user.ini’** file to a certain limit. With regard to these fixes, you can always get help from our support team, the **Helpful Humans** at Liquid Web!

### **Common Question #4: Why am I getting the “W3 Total Cache Error: Some files appear to be missing or out of place”?**

**W3 Total Cache** object caching can cause this issue. Disabling object caching and optionally removing **wp-content/object-cache.php** should fix this.
