Hi,
I have the same problem, since several weeks we have “Service Temporarily Unavailable” errors and I have several alerts about the memory size.
In the past I have followed your recommandation and I have increased the limit to 256MB.
Since 2 days I have disabled the translate plugin and now I don’t have anymore these problems.
The site is https://coeurgrenadine.fr
We would like to use your great plugin but it seems it need some optimization about the memory consumption.
