Hello,
since the past week we are having these kinds of issue. Memory is set in 128Mb.
We tried desactivating plugins, then using plugins for testing performance and we don`t know what to do. The web was working well the last three months, but it changes its behaviour since Tue, 10 without any modification by our side.
Please, we need to fix it asap, we worked all these days trying in order to fix it but we have no results.
Also WP-Admin console is ralentized and sometimes shows 500 Internal Server Error or Out of Memory.
Thanks and regards,
Claudio
