The error message you are receiving indicates that your PHP script has exceeded the memory limit allocated by PHP. Increasing the PHP memory limit to 2GB should be more than enough for most applications, but it's possible that your application is using more memory than anticipated.
The size of your database may contribute to the issue if you are loading large datasets into memory or running complex queries that require significant memory usage. However, it's important to note that the size of your database alone should not cause your application to exceed the memory limit.
There are a few potential solutions you could try:
Optimize your code: Review your code to identify any areas https://www.tellhappystar.org/ where you could be using more memory than necessary. For example, you could optimize loops, reduce the number of database queries, or use more efficient data structures.
Increase memory limit: You could try increasing the memory limit further. However, increasing the memory limit too much could cause other issues, such as slowing down your server or causing it to run out of memory.
Use pagination: If you're loading large amounts of data into memory, consider using pagination to limit the amount of data loaded at once.
Use caching: You could use caching to reduce the amount of data loaded from the database on each request. This can help reduce memory usage and improve performance.
Optimize database: Consider optimizing your database, such as indexing tables or removing unnecessary data, to reduce the amount of memory required to run queries.
