Updating plugins from the admin doesn't work

Question

Suddenly getting this strange error every time I try to update Craft or any plugins through the admin;

Status: Internal Server Error

Response: <pre>PHP Fatal Error &#039;yii\base\ErrorException&#039; with message &#039;Allowed memory size of 134217728 bytes exhausted (tried to allocate 4096 bytes)&#039; 

in /Users/a/Sites/askrembla/vendor/composer/composer/src/Composer/DependencyResolver/Solver.php:220

Stack trace:
#0 [internal function]: yii\base\ErrorHandler-&gt;handleFatalError()
#1 {main}</pre>

Memory and all that is fine as far as I can tell, so not sure why this error is thrown. Will continue investigating on my end.

Answer 1

Memory is definitely not fine, the error message is very explicit:

Allowed memory size of 134217728 bytes exhausted

You need to raise your PHP memory limits. Craft requires a minimum of 256MB to run properly.
