XF 2.1 ErrorException: Fatal Error: Out of memory (allocated 35651584) (tried to allocate 4096 bytes)

[ShikiSuen]

I got these errors happening everytime I do mass modification to templates or something similar (i.e. replacing the Terms and Rules article content.)

My server is Vultr VPS which uses the cheapest plan. MySQL Ngram smallest length is 2 (for searching Chinese texts).
Database Table types are default, but the index table has NGRAM enabled. Also, all tables use utf8mb4_unicode_520_ci for maximum compatibility with both Chinese and Japanese languages.

The memory_limit setting is not your problem, but the available memory of your server (VPS?) is.

Where exactly should I look?

As said before, you most likely need more memory.
So far you havn't given any information about your (virtual) hardware- how much memory do you have?
