Well Eduan, thanks for the response – at least there is one after 2 days.
But just claiming such behaviour has no relation to S2Members, without further analysis seems somewhat “bold” to me, to say the least. Especially as S2M had similar problems in the past, just browse thorugh your own forum on “htaccess”.
And it is a bit disapointing. I have every understanding, that the S2Members Team cannot allow to be drawn into all these interoperability problems between different plugins. But on the other hand, software problems are typically not just black and white, and it is a distinct possibility, that something from S2M has unwanted sideeffects. So at least I would have expected from S2M, to take a look at some logs or whatever you use to debug.
It is especially disappointing, as I activated my Membership and payed for S2M for the only reason to receive support. I have no real need for S2M Pro. And what I got up to now, does not justify the term “support” in my perception.
Concerning the ongoing Problem:
I have my htaccess now on 444 Readonly, as this seems to be the only way, I can protect my htaccess from being overwritten in an irregular Fashion. With 644 or higher, my blog runs into 500 internals Server error within hours.
Since my first call here two days ago, I am through with almost anything. I have gone through all the wordpress documentation regarding htaccess. I know all the common problems around htaccess. I have talked to my Server Provider about PHP Space and other distinct possibilities.
Furthermore I have deactivated any WP Plugin including S2Members, and the problem persist. Temporary I thought I had found the cause, as my plugin : “Better WP Security” had similar problems reported in the past (as S2M), but even after I completly wiped WP Security from my Installation, the problem persisted.
So I am still in the dark. And I have a conspicuous timely dependency on S2M. My blog has run for 15 month without any problems of such kind. And it has run with all the plugins I currently use. Just one week ago, I activated S2M. And S2M is definitly the last plugin I added. And S2M had similar problems with htaccess reported in past.
And exactly a few days after I activate S2M the problems begin to shop up. This is a curious coincidence. Possible ? Yes ! Probable ? No !
My feeling is, there is a sideeffect of S2M, something is written somewhere, where it shouldnt be written. And it is outside the plugin Directory, as the Problem persists with S2M deactivated.
So again, I dont expect wonders and I understand your need to protect yourself for being made responsible for every WP Problem in the world. But I would expect some more commitment to really verify, that S2M is unrelated to the Problem.
And I still need real help !
